fs/smbfs/proc.c: In function `smb_proc_readdir_long':
fs/smbfs/proc.c:2313: warning: comparison of unsigned expression < 0 is always false
fs/smbfs/proc.c:2467: warning: comparison of unsigned expression < 0 is always false

The first one is pretty dangerous looking, as smb_proc_readdir_long() can
return several negative error values and all those are converted to
unsigned and then erronously pass the test on line 2313.  Chris Wright gave
it a quick look and we did not see immediately if this can be remotely
exploited, but it looks pretty scary.

The second warning on line 2467 is just extra so I just removed it.
