[yocto] [yocto-autobuilder][PATCH 2/2] yoctogit.py: ensure mirrordir is set before trying to use it

[Bill Randle]

If OPTIMIZED_GIT_CLONE is False, it's possible for self.mirrordir to be
unset, which cause the _mirrorExists function to throw an exception. Check
that self.mirrordir is actually set before trying to use it.

[YOCTO #10010]

Upstream-Status: Inappropriate [embedded specific]
