Sometimes BADA, DEB or CEB error interrupts occur when sd card is unplugged during data transfer. These interrupts are currently ignored by the interrupt handler. But, this results in card not being recognised on subsequent insertion. This is because mmcqd is waiting forever for the data transfer(for which error occurred) to complete. Fix this, by reporting BADA, DEB, CEB errors to mmc-core as -EILSEQ, so that the core can do appropriate handling.
