f2fs: support iflag change given the mask
In f2fs_fileattr_set(),
if (!fa->flags_valid)
mask &= FS_COMMON_FL;
In this case, we can set supported flags by mask only instead of BUG_ON.
/* Flags shared betwen flags/xflags */
(FS_SYNC_FL | FS_IMMUTABLE_FL | FS_APPEND_FL | \
FS_NODUMP_FL | FS_NOATIME_FL | FS_DAX_FL | \
FS_PROJINHERIT_FL)
