mmc: core: Re-use code for MMC_CAP2_DETECT_ON_ERR in polling mode

Browse Source 
Previously the MMC_CAP2_DETECT_ON_ERR was invented for detecting
slow card removal. In was never a realy good solution and a proper
fix has been merged using gpio debouncing instead. We remove this
cap in this patch.

Although when using polling card detect mode, the code invented for
MMC_CAP2_DETECT_ON_ERR is re-used to complete card removal in an
earlier phase. There are no need waiting for the polling timeout to
elapse in this case.
