xhci: Allocate separate command structures for each LPM command
Every lpm commmand, both for USB 2 and USB 3 devies used the same
xhci->lpm_command structure to change max exit latency.
xhci->lpm_command is only protected by a hcd->bandwidth mutex, which is
not enoungh as USB 2 and USB 3 devices are behind separate HCDs.
Simplify code and avoid unnecessary locking risks by allocating
separate command structures for each lpm command, just like with
all other commands.
