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.
