iwlwifi: quiet a noisy printk

Timing issues in microcode for some devices can cause a compressed BA to
be sent to the driver prior to returning any a-MPDU notification.
Traces show RTS-CTS is exchanged and then the timer fires which causes an
empty BA to be sent which acknowledges nothing.  This results in a noisy
printk. Only print the message if the bitmap is non-zero.
