Pawel Laszczak 23115ca7d2 usb: cdns3: fix race condition before setting doorbell 
[ Upstream commit b69ec50b3e ]

For DEV_VER_V3 version there exist race condition between clearing
ep_sts.EP_STS_TRBERR and setting ep_cmd.EP_CMD_DRDY bit.
Setting EP_CMD_DRDY will be ignored by controller when
EP_STS_TRBERR is set. So, between these two instructions we have
a small time gap in which the EP_STSS_TRBERR can be set. In such case
the transfer will not start after setting doorbell.

Fixes: 7733f6c32e ("usb: cdns3: Add Cadence USB3 DRD Driver")
