Tetsuo Handa b2660f35d3 loop: remember whether sysfs_create_group() was done ...

commit d3349b6b3c upstream.

syzbot is hitting WARN() triggered by memory allocation fault
injection [1] because loop module is calling sysfs_remove_group()
when sysfs_create_group() failed.
Fix this by remembering whether sysfs_create_group() succeeded.
