PORTREVISION wasn't specified in net/intel-{ix,em}-kmod, which are
slave ports of net/intel-ixl-kmod. Because of that when PORTREVISION
was bumped in intel-ixl-kmod - it automatically appeared in the slave
ports, which shouldn't happen.
To avoid this in the future - explicitly specify PORTREVISION and
PORTEPOCH in the slave ports.
Sanity and compile tested using poudriere w/portlint.
