xhci: rework xhci internal endpoint halt state detection.

When xhci_requires_manual_halt_cleanup() was written it wasn't clear
that the xhci internal endpoint halt state always needs to be cleared
with a reset endpoint command. Functional stall cases additionally halt
the device side endpoint which requires class driver to clear the device
side halt with a CLEAR_FEATURE(ENDPOINT_HALT) request as well.

Clean up, rename, and make sure the new function always return true
when internal endpoint state is halted, including stall cases.

Based on related cleanup suggestion code by Niklas Neronin
