Dan Carpenter 0d04479857 ax25: uninitialized variable in ax25_setsockopt()
[ Upstream commit 9371937092 ]

The "opt" variable is unsigned long but we only copy 4 bytes from
the user so the lower 4 bytes are uninitialized.

I have changed the integer overflow checks from ULONG to UINT as well.
This is a slight API change but I don't expect it to break anything.

Fixes: a7b75c5a8c ("net: pass a sockptr_t into ->setsockopt")
