Peter Osterlund 46f4e1b7d5 [PATCH] packet driver permission checking fix 
If you tried to open a packet device first in read-only mode and then a
second time in read-write mode, the second open succeeded even though the
device was not correctly set up for writing.  If you then tried to write
data to the device, the writes would fail with I/O errors.

This patch prevents that problem by making the second open fail with
-EBUSY.
