net: dnet: remove unused variable 'tx_status 'in dnet_start_xmit()
Fixes the following W=1 kernel build warning(s):
drivers/net/ethernet/dnet.c:510:6: warning:
variable 'tx_status' set but not used [-Wunused-but-set-variable]
u32 tx_status, irq_enable;
^~~~~~~~~
After commit 4796417417a6 ("dnet: Dave DNET ethernet controller driver
(updated)"), variable 'tx_status' is never used in dnet_start_xmit(),
so removing it to avoid build warning.
