syscall: hoist Getsockname out of NetlinkRIB loops
Calling Getsockname once to fetch the Pid field from the *SockaddrNetlink
is necessary, but this data will remain static for the rest of the netlink
socket's lifetime. Moving this call and type assertion outside of the inner
loops will remove a number of unnecessary system calls.
