brcmfmac: fix 43455 CRC error under SDIO 3.0 SDR104 mode 

This patch fixes 43455 CRC error while running throughput test with
suspend/resume stress test.

The continuous failure messages before system crash:
brcmfmac: brcmf_sdiod_sglist_rw: CMD53 sg block read failed -84
brcmfmac: brcmf_sdio_rxglom: glom read of 25600 bytes failed: -5
brcmfmac: brcmf_sdio_rxfail: abort command, terminate frame
brcmfmac: brcmf_sdiod_sglist_rw: CMD53 sg block read failed -84
brcmfmac: brcmf_sdio_rxglom: glom read of 24576 bytes failed: -5
brcmfmac: brcmf_sdio_rxfail: abort command, terminate frame
