Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=44c635c60f78a693b5e6ad80e18c7e9a97a0c4cd



--------------------------------

[ Upstream commit d8ac9500 ]

Create a separate helper function to issue reset endpont commands
to clear halted endpoints.

This is useful for cases where a halted endpoint is discovered while
completing another command, and the endpoint halt needs to be cleared
with a endpoint reset first.

No functional changes
