can: xilinx_can: xcanfd_rx(): fix FSR register handling in the RX path

After commit c223da689324 ("can: xilinx_can: Add support for CANFD FD
frames") the driver is updating the FSR IRI index multiple times (i.e in
xcanfd_rx() and xcan_rx_fifo_get_next_frame()), It should be updated
once per RX packet. This patch fixes this issue, also this patch removes
the unnecessary fsr register checks in xcanfd_rx() API.
