irda: Removed all unused timeval variables
In the file au1k_ir.c & via-ircc.h, there were two unused definitions of the timeval type members, this commit therefore removes this unneeded code. In other three files, the same problem is the rx_time member is only ever written, never read, so removed it entirely.
