From: Niklas Neronin <niklas.neronin@linux.intel.com>

Simplifying the handle_tx_event() function by addressing the complexity
of its while loop. Replaces specific 'goto cleanup' statements with
'return' statements, applicable only where 'ep->skip' is set to 'false',
ensuring loop termination.

The original while loop, combined with 'goto cleanup', adds unnecessary
complexity. This change aims to untangle the loop's logic, facilitating a
more straightforward review of the upcoming comprehensive rework.
