cbfs: Check return value of map() for error
The CBFS core checks the result of a media->map() operation in multiple
places for CBFS_MEDIA_INVALID_MAP_ADDRESS, suggesting that this is a
valid response. However, it ironically fails to do so when actually
mapping the CBFS file itself, which can fail on buffer-constrained
systems since the size is much larger than when mapping metadata. This
patch adds a check with an error message and a NULL pointer return for
that case to make it easier to understand this condition.
