usb: gadget: storage: increase maximum storage num buffers
With a default size of 16kiB and with maximum of 32 buffers, we can transfer up to 512kiB, however Linux can transfer up to 1MiB in a single mass storage block transfer to USB3 storage devices. Because of this, 1MiB block transfers end up being slower than 512kiB block transfers. Let's increase maximum number of storage buffers to a ridiculous amount (256) so that anybody wanting to test maximum achievable throughput can do so.

Usually 2 buffers are enough to establish a good buffering
