btrfs: subpage: remove btrfs_fs_info::subpage_info member
The member btrfs_fs_info::subpage_info stores the cached bitmap start
position inside the merged bitmap.
However in reality there is only one thing depending on the sectorsize,
bitmap_nr_bits, which records the number of sectors that fit inside a
page.
The sequence of sub-bitmaps have fixed order, thus it's just a quick
multiplication to calculate the start position of each sub-bitmaps.
