[PATCH 3/8] iomap: Move lockdep_assert_held() to iomap_dio_rw() calls

From: Goldwyn Rodrigues <rgoldwyn@suse.com>

Filesystems such as btrfs can perform direct I/O without holding the
inode->i_rwsem in some of the cases like writing within i_size.
So, remove the check for lockdep_assert_held() in iomap_dio_rw()
