02f220b526 wifi: ipw2x00/lib80211: move remaining lib80211 into libipw
There's already much code in libipw that used to be shared
with more drivers, but now with the prior cleanups, those old
Intel ipw2x00 drivers are also the only ones using whatever is
now left of lib80211. Move lib80211 entirely into libipw.

3a3d1afd25 wifi: lib80211: Handle const struct lib80211_crypto_ops in lib80211
lib80211_register_crypto_ops() and lib80211_unregister_crypto_ops() don't
modify their "struct lib80211_crypto_ops *ops" argument. So, it can be
declared as const.

Doing so, some adjustments are needed to also constify some date in
"struct lib80211_crypt_data", "struct lib80211_crypto_alg" and the
return value of lib80211_get_crypto_ops().

260a9ad944 ipw2x00: potential buffer overflow in libipw_wx_set_encodeext()
The "ext->key_len" is a u16 that comes from the user.  If it's over
SCM_KEY_LEN (32) that could lead to memory corruption.

f35ba45c39 ipw2x00: Use scnprintf() for avoiding potential buffer overflow
Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

0e139e97f5 ipw2x00: remove redundant variables len, ret, reason and crypt
Variables len, ret, reason and crypt are assigned values that
are never read, hence they are redundant and can be removed.

Note: For the variable ret, a return code is being assigned, but
this is not returned and 0 is currently being returned, I believe
this is OK.

Cleans up clang warnings:
warning: variable 'len' set but not used [-Wunused-but-set-variable]
variable 'ret' set but not used [-Wunused-but-set-variable]
warning: variable 'reason' set but not used [-Wunused-but-set-variable]
warning: variable 'crypt' set but not used [-Wunused-but-set-variable]
