net: cadence_gem: Fix Tx descriptor update

The local variable "desc" was being used to read-modify-write the
first descriptor (of a multi-desc packet) upon packet completion.
desc however continues to be used by the code as the current
descriptor. Give this first desc RMW it's own local variable to
avoid trampling.
