[PATCH 1/6] driver/net/irda: Removed all unused timeval variables

[Chunyan Zhang]

In the file au1k_ir.c & via-ircc.h, there were two unused
definitions of the timeval type members, so I removed them
entirely in this patch.

In other three files, the same problem is the rx_time
member is only ever written, never read, so removed it
entirely.
