tests: Skip rc_flush tests if not supported in kernel

Older kernels (<6.2) that doesn't support IBV_ACCESS_FLUSH_GLOBAL return EINVAL on MR registration with this flag. This makes rc_flush tests to fail on such kernels. Fix this by skipping those test if EINVAL has been returned. Signed-off-by: Michael Margolin <[email protected]>
