FAT: add 'errors' mount option
On severe errors FAT remounts itself in read-only mode. Allow to
specify FAT fs desired behavior through 'errors' mount option:
panic, continue or remount read-only.
`mount -t [fat|vfat] -o errors=[panic,remount-ro,continue] \
<bdev> <mount point>`
This is analog to ext2 fs 'errors' mount option.
