[libvirt] [PATCH] lxc: remove redundant check

[ajia at redhat.com]

From: Alex Jia <ajia at redhat.com>

Detected by cppcheck, the previous function VIR_REALLOC_N(mounts, nmounts+1)
can make sure mounts is a none null value, so it is redundant to check if 
mounts is null.

* src/lxc/lxc_container.c: remove redundant check.
