Rene Rebe 037cf43531 floppy: fix for PAGE_SIZE != 4KB ...

commit 82d20481024cbae2ea87fe8b86d12961bfda7169 upstream.

For years I wondered why the floppy driver does not just work on
sparc64, e.g:

root@SUNW_375_0066:# disktype /dev/fd0
disktype: Can't open /dev/fd0: No such device or address

[  525.341906] disktype: attempt to access beyond end of device
fd0: rw=0, sector=0, nr_sectors = 16 limit=8
[  525.341991] floppy: error 10 while reading block 0

Turns out floppy.c __floppy_read_block_0 tries to read one page for
the first test read to determine the disk size and thus fails if that
is greater than 4k. Adjust minimum MAX_DISK_SIZE to PAGE_SIZE to fix
floppy on sparc64 and likely all other PAGE_SIZE != 4KB configs.
