[LTP] [PATCH] runltp: let each test acquire/release device

[Jan Stancek]

Problem with runltp creating and using single loop device for all tests
is that if one test fails/gets stuck or fails to umount loop device
for any reason, then all subsequent tests also fail, because
they try to use mounted device.

Don't force same loop device on all tests (unless it is chosen via
env. variable DEVICE) and let LTP library try to acquire and release
first usable loop device for each test.

Fixes #703
