omap_hsmmc: Flush posted write to IRQ

Spurious IRQs seen on MMC after 2.6.29.  Flush posted write in IRQ
handler.

The interrupt line is released by clearing the error status bits
in the MMCHS_STAT register, which must occur before the interrupt
handler returns to avoid unwanted irqs.  Hence the need to flush
the posted write.
