Both ibmvfc_show_host_(capabilities|npiv_version) functions retrieve values
from vhost->login_buf.resp buffer. This is the MAD response buffer from the
VIOS and as such any multi-byte non-string values are in big endian format.

Byte swap these values to host CPU endian format for better human
readability.
