[media] IR/streamzap: fix usec to nsec conversion

There is an integer overflow here because 0x03000000 * 1000 is too large
for 31 bits.

rawir.duration should be in terms of nsecs.
IR_MAX_DURATION and 0x03000000 are already in terms of nsecs.
STREAMZAP_TIMEOUT and STREAMZAP_RESOLUTION are 255 and 256 respectively
and are in terms of usecs.

The original code had a deadline of 1.005 seconds and the new code has a
deadline of .065 seconds.
