Subject: [PATCH v5 02/18] xfs: compat_ioctl: add missing conversions

FS_IOC_GETFSLABEL/FS_IOC_SETFSLABEL were added in linux-4.18
in xfs, but not in the compat_ioctl case, so add them here.

FITRIM was added earlier and also lacks a line the same function,
but this is ok because there is an entry in fs/compat_ioctl.c for
it.

Adding all three here to keep the native and compat ioctl handlers
in sync.
