[PATCH v2 0/2] net/netvsc: runtime queue reconfiguration and fixes

[Long Li]

This series adds support for runtime queue count reconfiguration in the
netvsc PMD, along with a prerequisite bug fix.

Patch 1 fixes a pre-existing subchannel resource leak in
eth_hn_dev_uninit() where subchannels are never closed before the
primary channel.

Patch 2 adds runtime queue count reconfiguration via port
stop/configure/start, with full NVS/RNDIS session teardown and reinit
when the queue count changes.

v2:
- Split subchannel leak fix into separate patch with Fixes tag (patch 1)
- Fix reinit_failed recovery: re-map device before chan_open when device
  is unmapped to prevent undefined behavior on unmapped ring buffers
- Move hn_rndis_conf_offload() to after reinit block so offload config
  targets the final RNDIS session instead of being lost on teardown
- Use write lock in hn_vf_tx/rx_queue_release() to prevent race with
  concurrent fast-path readers holding read lock
- Reset RSS indirection table to queue 0 in subchan_cleanup error path
- Fix multi-line comment style to follow DPDK convention
