mmc: Run fsck on the alternate image and hostfw

Before mounting the alternate image, run fsck on it to determine if the
filesystem is corrupted, this could happen if the BMC rebooted in the
middle of a code update for example. Invalidate the image if it's found
to be corrupted.

Run fsck on the hostfw partition too, this is a writable partition that
can benefit from autocorrection. The mmc initramfs runs fsck on the rwfs
partition already. It's a good practice to run fsck on writable
partitions. Do not fail if fsck fails on the hostfw partition, if it's
corrupted, an error would occur during the power on.

Tested: Verified there were no errors with this change. This change adds
about 1s to the execution of the mount service, from 5s to 6s to start:
