cbfs: Enforce media->map() result checking, improve error messages
If you try to boot a VBOOT2_VERIFY_FIRMWARE with less than 4K CBFS cache
right now, your system will try and fail to validate the FMAP signature
at (u8 *)0xFFFFFFFF and go into recovery mode. This patch avoids the
memcmp() to potentially invalid memory, and also adds an error message
to cbfs_simple_buffer_map() to make it explicit that we ran out of CBFS
cache space.
BUG=None
TEST=Booted on Veyron_Pinky with reduced CBFS cache, saw the message.
