[PATCH blktests] nvme/rc: fix rdma driver check

[Shin'ichiro Kawasaki]

Since the commit 4824ac3f5c4a ("Skip tests based on SKIP_REASON, not
return value"), blktests no longer checks return values of _have_foo
helpers. Instead, it checks if _have_foo helpers set SKIP_REASON, which
was renamed to SKIP_REASONS later, to judge test case skip. If two
_have_foo helpers are chained with ||, the skip check does not work as
expected since one of the helper may set SKIP_REASONS even when the
other does not set. Such chain with || is done in _nvme_requires() to
check rdma drivers.

To fix the check, do not chain the helper functions with || operator.
Instead, refer $use_rxe to call only the required function.
