[libvirt] [PATCH] fix build with gcc 4.8.5-4 and -Werror=inline option

[Maxim Nestratov]

fix numerous inlining errors like:

In file included from vircgroupmock.c:24:0:
In function 'stat':
virmock.h:259:1: error: inlining failed in call to 'callStat.part.1':
call is unlikely and code size would grow [-Werror=inline]
 callStat(int (*realStat)(const char *, struct stat *),
