MBR_read() can be reading from a file as well as a raw partition.
And files can be smaller (e.g. 512 bytes like /usr/mdec/mbr) than
a disk sector (e.g. 4096 bytes on pirofti's external disk drive).
So relax the length test on the read() result to < DEV_BSIZE (the
amount of data we actually want) instead of < secsize (the minimum
size that read() will accept).
'fdisk -e' and 'fdisk -i' now work on devices with sector sizes
greater than DEV_BSIZE.
