[PATCH] net/sunrpc/svcsock.c: fix a check

The return value of kernel_recvmsg() should be assigned to "err", not
compared with the random value of a never initialized "err" (and the "< 0"
check wrongly always returned false since == comparisons never have a
result < 0).

Spotted by the Coverity checker.
