1683149 ("usb: dwc3: gadget: Fix logical condition") was reverted
on importing android-4.19-q.90 into msm-4.19 as this change
prevented the adbd userspace daemon from ever receiving packets
from the kernel USB driver. android-4.19-q.95 introduced new
change ceaeb21b ("usb: dwc3: gadget: Fix request complete check")
that fixed the regression, hence it is safe to restore the revert.
It is done in this merge.
