Bug Description:
_test_mount function is failing with the following error:
./common/rc: line 4716: _xfs_prepare_for_eio_shutdown: command not found
check: failed to mount /dev/loop0 on /mnt1/test
when the second section in local.config file is xfs and the first section
is non-xfs.
It can be easily reproduced with the following local.config file
[s2]
export FSTYP=ext4
export TEST_DEV=/dev/loop0
export TEST_DIR=/mnt1/test
export SCRATCH_DEV=/dev/loop1
export SCRATCH_MNT=/mnt1/scratch
[s1]
export FSTYP=xfs
export TEST_DEV=/dev/loop0
export TEST_DIR=/mnt1/test
export SCRATCH_DEV=/dev/loop1
export SCRATCH_MNT=/mnt1/scratch
./check selftest/001
Root cause:
When _test_mount() is executed for the second section, the FSTYPE has
already changed but the new fs specific common/$FSTYP has not yet
been done. Hence _xfs_prepare_for_eio_shutdown() is not found and
the test run fails.
Fix:
Remove the additional _test_mount in check file just before ". commom/rc"
since ". commom/rc" is already sourcing fs specific imports and doing a
_test_mount.
Fixes: 1a49022fab9b4 ("fstests: always use fail-at-unmount semantics for XFS")

Don't we want to _test_mount the newly created filesystem still? But
perhaps after sourcing common/rc ?
--D
common/rc calls init_rc() in the end and init_rc() already does a
_test_mount. _test_mount after sourcing common/rc will fail, won't it?
Does that make sense?
