ublk: implement integrity user copy
Add a function ublk_copy_user_integrity() to copy integrity information
between a request and a user iov_iter. This mirrors the existing
ublk_copy_user_pages() but operates on request integrity data instead of
regular data. Check UBLKSRV_IO_INTEGRITY_FLAG in iocb->ki_pos in
ublk_user_copy() to choose between copying data or integrity data.
[csander: change offset units from data bytes to integrity data bytes,
fix CONFIG_BLK_DEV_INTEGRITY=n build, rebase on user copy refactor]
