sata_sil: ignore and clear spurious IRQs while executing commands by polling
sata_sil used to trigger HSM error if IRQ occurs during polling
command. This didn't matter because polling wasn't used in sata_sil.
However, as of 2.6.20, all IDENTIFYs are performed by polling and
device detection sometimes fails due to spurious IRQ. This patch
makes sata_sil ignore and clear spurious IRQ while executing commands
by polling.
This fixes bug#7996 and IMHO should also be included in -stable.
