[poky] [PATCH 43/57] cooker: fix UnboundLocalError when exception occurs during parsing

[Scott Garman]

From: Paul Eggleton <paul.eggleton at linux.intel.com>

Fix a recent regression where we see the following additional error
after an error occurs during parsing:

ERROR: Command execution failed: Traceback (most recent call last):
  File "/home/paul/poky/poky/bitbake/lib/bb/command.py", line 84, in runAsyncCommand
    self.cooker.updateCache()
  File "/home/paul/poky/poky/bitbake/lib/bb/cooker.py", line 1202, in updateCache
    if not self.parser.parse_next():
  File "/home/paul/poky/poky/bitbake/lib/bb/cooker.py", line 1672, in parse_next
    self.virtuals += len(result)
UnboundLocalError: local variable 'result' referenced before assignment

(Bitbake rev: 1ae0181ba49ccfcb2d889de5dd1d8912b9e49157)
