This patch fixes the following sparse warnings:
drivers/staging/lustre/lnet/klnds/socklnd/socklnd_cb.c:284:51: warning:
cast removes address space of expression
drivers/staging/lustre/lnet/klnds/socklnd/socklnd_cb.c:284:39: warning:
incorrect type in assignment (different address spaces)
drivers/staging/lustre/lnet/klnds/socklnd/socklnd_cb.c:284:39: expected
void [noderef] <asn:1>*iov_base
drivers/staging/lustre/lnet/klnds/socklnd/socklnd_cb.c:284:39: got
void *<noident>
by adding the __user attribute to the names of userspace pointer types in
the cast operators of ksocknal_recv_iov().
