Subject: fs/partition/msdos: fix unusable extended partition for > 512B sector
From: OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>
Smaller size than a minimum blocksize can't be used, after all it's
handled like 0 size.
For extended partition itself, this makes sure to use bigger size than one
logical sector size at least.
