accel/qaic: Remove redundant retry_count = 0 statement

If msg_xfer() is called and the channel ring does not have enough room
to accommodate the whole message, the function sleeps and tries again.
It uses retry_count to keep track of the number of retrials done. This
variable is not used after the space check succeeds. So, remove the
retry_count = 0 statement used later in the function.
