gfs2: Fix and clean up {GET,SET}FLAGS ioctl
Switch to a simple array for mapping between the FS_*_FL and GFS_DIF_*
flags. Clarify how the mapping between FS_JOURNAL_DATA_FL and the
filesystem flags works. The GFS2_DIF_SYSTEM flag cannot be set from
user space, so remove it from GFS2_FLAGS_USER_SET. Fail with -EINVAL
when trying to set flags that are not supported instead of silently
ignoring those flags.
Partially fixes xfstest generic/424.
