iomap: trace: Add missing flags to [IOMAP_|IOMAP_F_]FLAGS_STRINGS
This adds missing iomap flags to IOMAP_FLAGS_STRINGS &
IOMAP_F_FLAGS_STRINGS for tracing. While we are at it, let's also print
values of iomap->type & iomap->flags.
e.g. trace for ATOMIC_BIO flag set
xfs_io-1203 [000] ..... 183.001559: iomap_iter_dstmap: dev 8:32 ino 0xc bdev 8:32 addr 0x84200000 offset 0x0 length 0x10000 type MAPPED (0x2) flags DIRTY|ATOMIC_BIO (0x102)
e.g. trace with DONTCACHE flag set
xfs_io-1110 [007] ..... 238.780532: iomap_iter: dev 8:16 ino 0x83 pos 0x1000 length 0x1000 status 0 flags WRITE|DONTCACHE (0x401) ops xfs_buffered_write_iomap_ops caller iomap_file_buffered_write+0xab/0x0
