xfs: Set xfs_buf type flag when growing summary/bitmap files
The following sequence of commands,
mkfs.xfs -f -m reflink=0 -r rtdev=/dev/loop1,size=10M /dev/loop0
mount -o rtdev=/dev/loop1 /dev/loop0 /mnt
xfs_growfs /mnt
... causes the following call trace to be printed on the console,
XFS: Assertion failed: (bip->bli_flags & XFS_BLI_STALE) || (xfs_blft_from_flags(&bip->__bli_format) > XFS_BLFT_UNKNOWN_BUF && xfs_blft_from_flags(&bip->__bli_format) < XFS_BLFT_MAX_BUF), file: fs/xfs/xfs_buf_item.c, line: 331

This occurs because the buffer being formatted has the value of
XFS_BLFT_UNKNOWN_BUF assigned to the 'type' subfield of
bip->bli_formats->blf_flags.
This commit fixes the issue by assigning one of XFS_BLFT_RTSUMMARY_BUF
and XFS_BLFT_RTBITMAP_BUF to the 'type' subfield of
bip->bli_formats->blf_flags before committing the corresponding
transaction.
