Fix modprobe error handling.

modprobe was failing if you `modprobe a.ko`, then `modprobe b.ko` where b.ko
depends on a.ko --- b.ko will fail to load because a.ko is already loaded.
The code to handle this was incorrectly checking `rc` rather than `errno`
against EEXIST.

(We should pull the insmod.c equivalent of `ins_mod` out into lib/
and reuse it in modprobe.c, but I didn't want to get bogged down.)
