This patch removes an unneeded do while loop which
sends a control message to a usb device. In this case,
the loop executes once because usRetries is
initialized to zero. After the first iteration
this variable will be 1. Therefore, the statement:
"usRetries < MAX_RDM_WRM_RETIRES" will evaluate to
false causing the do while statement to execute
once because MAX_RDM_WRM_RETIRES is equal to 1.
