nvmeof-mp/rc: Avoid skipping tests due to the expected SKIP_REASON

In _have_kernel_option(), SKIP_REASON = "kernel option NVME_MULTIPATH
has not been enabled" is expected but all nvmeof-mp tests are skipped
due to the SKIP_REASON. For example:
-----------------------------------------------------
./check nvmeof-mp/001
nvmeof-mp/***                                                [not run]
    kernel option NVME_MULTIPATH has not been enabled
-----------------------------------------------------

Avoid the issue by unsetting the SKIP_REASON.
