[PATCH v2 1/9] ima: based on policy verify firmware signatures (pre-allocated buffer)

[Mimi Zohar <zohar@xxxxxxxxxxxxxxxxxx>]

Don't differentiate between kernel_read_file_id READING_FIRMWARE and
READING_FIRMWARE_PREALLOC_BUFFER enumerations.

Fixes: a098ecd firmware: support loading into a pre-allocated buffer (since 4.8)
