[blktests,0/6] fix module check issues

Message

Current blktests have unexpected test case failures caused by module
availability checks. This series addresses two issues related to module check
and fix the failures.

The first issue is caused by module load by _have_driver(). When this helper
function checks the specified module (or driver) is available, it loads the
module using modprobe command. It leaves the module loaded and affects following
test cases. The first patch addresses this issue. The second patch avoids side
affects of the first patch on nbd test cases.

The second issue is in _have_modules(). Recently, _have_driver() helper function
was introduced to provide similar but different feature from _have_modules().
However, it turned out that _have_modules() is not working as expected and does
exactly same check as _have_driver(). The third patch fixes _have_module() to
work as expected. This change makes block/001 and srp test group skipped.
Following three patches adjust skip conditions not to skip the test cases.

Shin'ichiro Kawasaki (6):
  common/rc: avoid module load in _have_driver()
  nbd/rc: load nbd module explicitly
  common/rc: ensure modules are loadable in _have_modules()
  common,tests: replace _have_driver() with _have_drivers()
  block/001: use _have_drivers() in place of _have_modules()
  srp/rc: allow test with built-in sd_mod and sg drivers
