ssb: sdio: Don't overwrite const buffer if block_write fails
It doesn't make sense to clobber the const driver-side buffer, if a write-to-device attempt failed. All other SSB variants (PCI, PCMCIA and SoC) also don't corrupt the buffer on any failure in block_write. Therefore, remove this memset from the SDIO variant.
