[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.
