lockd: fix arg parsing for grace_period and timeout.
commit de5b8e8e047534aac6bc9803f96e7257436aef9c upstream.
If you try to set grace_period or timeout via a module parameter
to lockd, and do this on a big-endian machine where
sizeof(int) != sizeof(unsigned long)
it won't work. This number given will be effectively shifted right
by the difference in those two sizes.
So cast kp->arg properly to get correct result.
