kernel: kexec_file: fix error return code of kexec_calculate_store_digests()
[ Upstream commit 31d82c2c787d5cf65fedd35ebbc0c1bd95c1a679 ]
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.
