address Bug 203440 - Fixed documentation grammar

Summary

This seems to be an attempt to clarify the sentence. A little more rearrangement might help:

Each returned
.Li addrinfo
structure contains three members that are suitable for a call to
.Xr socket 2 :
.Fa ai_family ,
.Fa ai_socktype ,
and
.Fa ai_protocol .

Breaking the sentence might help even more.

head/lib/libc/net/getaddrinfo.3

254

Needs a space before the final period, or it is counted as part of the argument.

.Fa ai_protocol .

The bug reporter didn't really say what their complaint was, but this is clearer and better.

Please remember to update .Dd, check with igor and mandoc -Tlint, and set for MFC after 1 week. Thanks!
