Revert "usb: musb: host: don't start next rx urb if current one failed"

This reverts commit dbac5d07.

commit dbac5d07 ("usb: musb: host: don't start next rx urb if current one failed")
along with commit b5801212 ("usb: musb: host: clear rxcsr error bit if set")
try to solve the issue described in [1], but the latter alone is
sufficient, and the former causes the issue as in [2], so now revert it.
