tests: Remove maximum version kernel check.

The macro 'OVS_CHECK_KERNEL' was checking for maximum supported kernel
version.  This means checks like 'OVS_CHECK_KERNEL(3, 10, 4, 18)'
in various tests need to be updated when each new kernel version is
supported. This is unnecessary as these tests are expected to continue
to work in later kernel versions.

Fix this by changing the macro to check for minimum version only and
update the macro name accordingly.

This patch does not make any possible corrections to the indicated minimum
kernel version specified by the callers of the macro.
