can: flexcan: flexcan_irq(): rename variable reg_iflag -> reg_iflag_rx

Browse Source 
This patch renames the variable reg_iflag in the flexcan_irq() function
to reg_iflag_rx. This better reflects the contents of the varibale. It
does not hold the unmodified iflag registers, instead all non RX
interrupts have been masked.
