* Don't let users format a volume with more sectors than can fit in
the 32 bits that the FAT spec provides for storing the sector count on
disk. Since dosfs_initialize() assumes 512-byte sectors, this
will truncate FAT volumes at ~2.2 TB when a user tries for format
a partition larger than that.
* Mount read-only if the sector count read from disk is lower than it
should be.
* Account for an unrelated overflow in struct device_geometry that
could theoretically occur when mounting a large FAT image file.
* Set the struct mount read-only flag earlier during mounting, to
avoid a fillinusemap error when changing to read-only inside
fat_volume_init.
* Addresses #19079.
