net: mana: Add debug knob to skip TX timeout recovery reset

Browse source

Add a per-port debugfs boolean "tx_timeout_skip_reset" that, when
enabled, makes mana_tx_timeout() log the TX timeout and return without
queueing the per-port detach/attach recovery work.

This is a debug-only aid for bringup and qualification: skipping the
recovery reset keeps the device and queue state intact so a TX timeout
can be correlated with hardware telemetry. The knob defaults to false,
so production recovery behaviour is unchanged.
