Jia-Ju Bai 0886bb143c kernel: kexec_file: fix error return code of kexec_calculate_store_digests() 
[ Upstream commit 31d82c2c78 ]

When vzalloc() returns NULL to sha_regions, no error return code of
kexec_calculate_store_digests() is assigned.  To fix this bug, ret is
assigned with -ENOMEM in this case.
