pxe_dns: remove obsolete pxe_dns.c wrapper
We used to need a wrapper around the core function dns_resolv() to implement pxe_dns(), because the former function required its argument to live in low memory. This is no longer the case and hasn't been for a while, so remove this unnecessary level of indirection. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
