[PATCH V2 7/8] loop: remove extra variable in lo_req_flush

From: Chaitanya Kulkarni <kch@nvidia.com>

The local variable file is used to pass it to the vfs_fsync(). We can
get away with using lo->lo_backing_file instead of storing in a local
variable which is not used anywhere else.

No functional change in this patch.
