lib/nvme_tcp: check destination port before parsing address

Browse Source 
nvme_tcp_parse_addr() uses getaddrinfo() to parse the address.
Depending on the system behavior of this function differs.
On FreeBSD the port is verified not to be exceeding 65535
for IPv4, meanwhile Linux does not check it at this point.

test_nvme_tcp_qpair_connect_sock() UT was attempting to
test the code path that is moved in this patch, but
on FreeBSD was encountering failure during getaddrinfo()
with different error code.

This patch moves the destination port check before
parsing addresses to take the same path regardless of
the system used.

Fixes #2936
