iget: stop the MINIX filesystem from using iget() and read_inode()

Stop the MINIX filesystem from using iget() and read_inode().  Replace
minix_read_inode() with minix_iget(), and call that instead of iget().
minix_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.

minix_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
