[PATCH 2/2] Don't fatal_error if required mounts are already mounted

[Will Woods <wwoods redhat com>]

Change loader/init.c so it doesn't bother checking the return value
of mount(). Instead it just checks to see if the mount functions as
expected - for example, after mounting /proc it checks to see if
/proc/cmdline exists.
