Subject: [PATCH] libnpclient: noinline npc_gets

gcc-15 Factory builds are failing with:
[   20s] In function 'npc_gets',
[   20s]     inlined from 'cmd_showmount' at diodcli.c:496:12:
[   20s] ../libnpclient/read.c:218:19: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]

[   20s]       |          ^
[   21s] lto1: all warnings being treated as errors

I've taken a quick look, and don't think that 'done' can cause a 'buf'
overrun here, but I may be wrong (the code is pretty hairy).

Attempt to workaround the compiler error by avoiding npc_gets inlining.
