iwlwifi: read the Rx write pointer only once The FH (DMA engine) tells the driver the index of the last ready (closed) Rx buffer. This data is in closed_rb_num. If we read this data several times we may get inconsistencies between the code and the debug prints which can make it harder to debug issues here.
