ssb: sdio: Don't overwrite const buffer if block_write fails

commit 47ec636f7a25aa2549e198c48ecb6b1c25d05456 upstream.

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.
