USB8XXX_FW_MAX_RETRY is 3.  We were using a post-op loop
"while (retries--) {" but then the lines after that assume the loop
exits with retries set to zero.

I've fixed this by changing to a pre-op loop.  I started with retries
set to 4 instead of 3 so that we still go through the loop the same
number of times.

'struct timeval' uses a 32-bit seconds field which will overflow in
year 2038 and beyond. This patch is part of a larger effort to remove
all instances of 'struct timeval' from the kernel and replace them
with 64-bit timekeeping variables.
The patch also fixes the debug printf specifier to avoid the
seconds value being truncated.
The patch was build-tested / debugged by removing the
"if VERBOSE > SHOW_ERROR_MESSAGES" guards.
