xhci: Do not set the CRCR_CS bit
We do not need to set the CS (Command Stop) bit in the Command Ring
Control Register. CS is implied by CA (Command Abort). I'm not sure if
there is a defined execution order for these command bits, so it's
safer to only use the CA bit as it includes the CS function.
Ref: xHCI spec 1.2 (May 2019), Section 5.4.5, Table 5-24.
BUG=b:160354585,b:157123390
