[libvirt] [PATCH] Fix missing char dev lock path case in configure

[Roman Bogorodskiy]

configure check for character devices lock path calls
AC_DEFINE_UNQUOTED for VIR_CHRDEV_LOCK_FILE_PATH even if
$with_chrdev_lock_files = "no".

So the locking code in conf/virchrdev.c:

 #ifdef VIR_CHRDEV_LOCK_FILE_PATH

is compiled in even if it shouldn't, because VIR_CHRDEV_LOCK_FILE_PATH
is defined as "no", so it tries to create lock files with strange
lock path like 'no/LCK..'.

Fix that by calling AC_DEFINE_UNQUOTED only if $with_chrdev_lock_files
is not 'no'.
