virtio_mem: fix hardcoded 'vm' variable in bbm iteration macros

Browse Source 
virtio_mem_bbm_for_each_bb() and virtio_mem_bbm_for_each_bb_rev()
accept a '_vm' parameter to allow callers to pass any variable name
referring to the virtio_mem instance. However, the 'for' loop
initializer and part of the loop condition use the bare name 'vm'
instead of the macro parameter '_vm'.

Fix by replacing all bare 'vm->' references inside the macros with
the '_vm' parameter, and wrap in parentheses following kernel macro
conventions.
