[Qemu-trivial] [PULL 16/23] migration: Remove unneeded NULL check from m

From: Michael Tokarev
Subject: [Qemu-trivial] [PULL 16/23] migration: Remove unneeded NULL check from migrate_fd_error()
Date: Fri, 28 Oct 2016 18:18:47 +0300

From: Peter Maydell <address@hidden>

All the callers of migrate_fd_error() pass a non-NULL
error parameter, and if any did pass NULL then we would
segfault in error_copy(), so remove the unnecessary
NULL check earlier in the function.
(Spotted by Coverity.)
