net: ipv4: Fix truncated timestamp returned by inet_current_timestamp()

The millisecond timestamps returned by the function is
converted to network byte order by making a call to htons().
htons() only returns __be16 while __be32 is required here.

This was identified by the sparse warning from the buildbot:
net/ipv4/af_inet.c:1405:16: sparse: incorrect type in return
    expression (different base types)
net/ipv4/af_inet.c:1405:16: expected restricted __be32
net/ipv4/af_inet.c:1405:16: got restricted __be16 [usertype] <noident>

Change the function to use htonl() to return the correct __be32 type
instead so that the millisecond value doesn't get truncated.
