PM / Hibernate: Use get_gendisk to verify partition if resume_file is integer format
Sometimes resume= parameter comes in integer style (e.g. major:minor)
and then name_to_dev_t can not detect partition properly. (especially
async device like usb, mmc).
This patch calls get_gendisk() if resumewait is true and resume_file
is in integer format to work around this problem.
