Zizhi Wo 09ecf8f550 cachefiles: Clean up in cachefiles_commit_tmpfile() ...

Currently, cachefiles_commit_tmpfile() will only be called if object->flags
is set to CACHEFILES_OBJECT_USING_TMPFILE. Only cachefiles_create_file()
and cachefiles_invalidate_cookie() set this flag. Both of these functions
replace object->file with the new tmpfile, and both are called by
fscache_cookie_state_machine(), so there are no concurrency issues.

So the equation "d_backing_inode(dentry) == file_inode(object->file)" in
cachefiles_commit_tmpfile() will never hold true according to the above
conditions. This patch removes this part of the redundant code and does not
involve any other logical changes.
