net: mana: Improve the HWC error handling

Browse source

Currently when the HWC creation fails, the error handling is flawed,
e.g. if mana_hwc_create_channel() -> mana_hwc_establish_channel() fails,
the resources acquired in mana_hwc_init_queues() is not released.

Enhance mana_hwc_destroy_channel() to do the proper cleanup work and
call it accordingly.
