sbat: include NULL terminator when calculating buffer end in parse_sbat()

Browse Source 
The parse_sbat() function is currently removing the last character of the
passed buffer, which will usually be a null-terminated string to parse.

There's no reason to do this and just take the whole size as specified by
the caller.
