This patch fixes two bugs introduced by commit c0bd48bb3e
("usb: xhci: set xhci trb ent quirk based on platform data").
1. Connect with VFAT USB 3.0 disk, do "mount" command cause
the error log:
usb 8-1: reset SuperSpeed USB device number 2 using xhci-hcd
sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK

blk_update_request: I/O error, dev sda, sector 3497
2. Connect with USB 3.0 disks which support UAS mode, mount
fail with the error log:

It's because that in the above two cases, the transfer length
of the first TRB in the URB maybe not an integer multiple of
the EP maxpacket, and if we enable the ENT flag in the any
TRB of the URB, it will cause xHCI babble error.
This patch avoids to enable the ENT flag if the transfer
length of the first TRB isn't an integer multiple of the
EP maxpacket, or if the EP support bulk streaming protocol.
