Subject: [PATCH] xen-pciback: Add name prefix to global 'permissive' variable

commit 8014bcc86ef112eab9ee1db312dba4e6b608cf89 upstream.

The variable for the 'permissive' module parameter used to be static
but was recently changed to be extern.  This puts it in the kernel
global namespace if the driver is built-in, so its name should begin
with a prefix identifying the driver.
