Subject: [PATCH 1/2] check: source common/rc again if TEST_DEV was recreated

From: Eryu Guan <eguan@...hat.com>

If TEST_DEV is recreated by check, FSTYP derived from TEST_DEV
previously could be changed too and might not reflect the reality.
So source common/rc again with correct FSTYP to get fs-specific
configs, e.g. common/xfs.

For example, using this config-section config file, and run section
ext4 first then xfs, you can see:

our local _scratch_mkfs routine ...
./common/rc: line 825: _scratch_mkfs_xfs: command not found
check: failed to mkfs $SCRATCH_DEV using specified options

local.config:
[default]
RECREATE_TEST_DEV=true
TEST_DEV=/dev/sda5
SCRATCH_DEV=/dev/sda6
TEST_DIR=/mnt/test
SCRATCH_MNT=/mnt/scratch

[ext4]
MKFS_OPTIONS="-b 4096"
FSTYP=ext4

[xfs]
FSTYP=xfs
MKFS_OPTIONS="-f -b size=4k"
