[ Upstream commit 428805c0c5e76ef643b1fbc893edfb636b3d8aef ]
get_gendisk grabs a reference on the disk and file operation, so this code will leak both of them while having absolutely no use for the gendisk itself.
This effectively reverts commit 2df83fa4bce421f ("PM / Hibernate: Use get_gendisk to verify partition if resume_file is integer format")
