bdev/nvme: Merge completing reset_io into _bdev_nvme_reset_complete()

Browse Source 
reset_io is stored into nvme_bdev_ctrlr->reset_bio now. Hence we can
merge completing reset_io into _bdev_nvme_reset_complete() easily.
i
As a few minor changes, to reduce the size of the following patches,
clear reset_bio before calling spdk_bdev_io_complete(), and call
spdk_bdev_io_complete() after completing ctrlr reset.

The following patches will retry pending reset_ios if reset is internal,
abort reset_ios if reset is external and fails, or succeed reset_ios
if reset is external and succeeds.

This clean-up will be helpful for such enhancement.
