iomap: Add some uptodate state handling helpers for ifs state bitmap

Browse source

This patch adds two of the helper routines ifs_is_fully_uptodate()
and ifs_block_is_uptodate() for managing uptodate state of "ifs" state
bitmap.

In later patches ifs state bitmap array will also handle dirty state of all
blocks of a folio. Hence this patch adds some helper routines for handling
uptodate state of the ifs state bitmap.
