sd-as3525v2: panic in case of error in the isr

Disable errors on response timeout since it can happen on SD_SEND_IF_COND
Disable errors on start bit error : it's ignored by the linux driver

No panic on my side with those 2 bits unchecked, but no transfer
completion either.
Note: the Linux driver doesn't implement DMA
