s390/crc32: Remove have_vxrs static key
Replace the have_vxrs static key with a cpu_has_vx() call. cpu_has_vx() resolves into a compile time constant (true) if the kernel is compiled for z13 or newer. Otherwise it generates an unconditional one instruction branch, which is patched based on CPU alternatives. In any case the generated code is at least as good as before and avoids static key handling.
