ath3k devices fail to load firmwares on xHCI buses, but work well on
EHCI, this might be a compatibility issue between xHCI and ath3k chips.
As my testing result, those chips will work on xHCI buses again with
this patch.

This workaround is from Qualcomm, they also did some workarounds in
Windows driver.

In this expression: seq = (seq - 1) % 8 seq (u8) is implicitly converted to an int in the arithmetic operation. So if seq value is 0, operation is ((0 - 1) % 8) => (-1 % 8) => -1. The new seq value is 0xff which is an invalid ACK value, we expect 0x07. It leads to frequent dropped ACK and retransmission. Fix this by using '&' binary operator instead of '%'.
