Dan Carpenter 845f04c063 netrom: fix api breakage in nr_setsockopt()
BugLink: https://bugs.launchpad.net/bugs/1959376

[ Upstream commit dc35616e6c ]

This needs to copy an unsigned int from user space instead of a long to
avoid breaking user space with an API change.

I have updated all the integer overflow checks from ULONG to UINT as
well.  This is a slight API change but I do not expect it to affect
anything in real life.
