minix: Add required sanity checking to minix_check_superblock()

In the Linux kernel, the following vulnerability has been resolved:

minix: Add required sanity checking to minix_check_superblock()

The fs/minix implementation of the minix filesystem does not currently
support any other value for s_log_zone_size than 0. This is also the
only value supported in util-linux; see mkfs.minix.c line 511. In
addition, this patch adds some sanity checking for the other minix
superblock fields, and moves the minix_blocks_needed() checks for the
zmap and imap also to minix_check_super_block().

This also closes a related syzbot bug report.
