usb: uas: ignore UAS for Seagate Expansion Portable Drive

Browse Source 
The Seagate Expansion Portable Drive HDD (idVendor=0bc2, idProduct=2321) is reported to fail to work on rockchip platforms
with the following error message when do read/write operation by dd command:

xhci-hcd xhci-hcd.11.auto: Ring expansion failed

According to tkaiser's suggestion[1], we can try to increase the kernel's
coherent-pool memory size to fix this issue. The kernel coherent-pool memory
size was limited at 256KB by default. When set the DEFAULT_DMA_COHERENT_POOL_SIZE
to 1MB, the error "Ring expansion failed" can be fixed, but it still not
work with the other error message:

xhci-hcd xhci-hcd.12.auto: ERROR Unknown event condition 34 for slot 1 ep 3 , HC probably busted
sd 0:0:0:0: [sda] tag#16 uas_eh_abort_handler 0 uas-tag 17 inflight: CMD OUT
...
scsi host0: uas_eh_bus_reset_handler start
xhci-hcd xhci-hcd.12.auto: ERROR Transfer event for disabled endpoint slot 1 ep 6 or incorrect stream ring

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this HDD.
