This patch changes fsg_common_set_nluns() to fsg_common_set_max_luns()
which now only allocates an empty array for luns and set nluns
to 0. While LUNS are create we simply count them and store result
in nluns which is send later to host.

At this point I would just change common->luns to be an array rather
than a pointer. This would remove need for max_luns all together.
Sounds like a good idea and I also though about it but I gave up due to
memory usage. Most legacy gadgets reduce size of allocated luns array to
number of received luns in module params. Adding array with static size
will make this impossible. If we may don't care about this ~80 bytes I
will be happy make common->luns array as it simplifies the code.
