The stored 'blk' value is overwritten to 'size / 512' before it can
be used in usb_stor_set_max_xfer_blk(). This is not what we want.
In fact, when 'size' exceeds the upper limit (USHRT_MAX * 512), we
should simply assign 'size' to the upper limit.

The 'Max Burst Size' indicates to the xHC the maximum number of
consecutive USB transactions that should be executed per scheduling
opportunity. This is a “zero-based” value, where 0 to 15 represents
burst sizes of 1 to 16, but at present this is always set to zero.
Let's program the required value according to real needs.

USB endpoint reports the period between consecutive requests to send
or receive data as bInverval in its endpoint descriptor. So far this
is ignored by xHCI driver and the 'Interval' field in xHC's endpoint
context is always programmed to zero which means 1ms for low speed
or full speed , or 125us for high speed or super speed. We should
honor the interval by getting it from endpoint descriptor.
