Subject: virpcimock: Initialize real_close before using it
X-Git-Tag: v6.10.0-rc1~352

virpcimock: Initialize real_close before using it

real_close() is not inialized by the first invocation of close(). That
causes an issue when the mock is used before others and a call of
real_close() results in a jump to NULL pointer.
