md: fix max sectors calculation for super 1.0
To grow size of super 1.0 raid array, it is necessary to check the device
max usable size.
Now it uses rdev->sectors for max usable size. If one disk is 500G and the
raid device only uses the 100GB of this disk. rdev->sectors can't tell the
real max usable size. The max usable size should be
dev_size-(superblock_size+bitmap_size+badblock_size).
Also, remove unnecessary sb_start update in super_1_rdev_size_change().
