ar9170usb: fix panic triggered by undersized rxstream buffer
commit 879999cec9489f8942ebce3ec1b5f23ef948dda7 upstream.
While ar9170's USB transport packet size is currently set to 8KiB,
the PHY is capable of receiving AMPDUs with up to 64KiB.
Such a large frame will be split over several rx URBs and
exceed the previously allocated space for rx stream reconstruction.
This patch increases the buffer size to 64KiB which is
in fact the phy & rx stream designed size limit.
