mmc: core: Claim host while freeing card
When SD/MMC card is removed without unmounting and then reinserted again while gendisk is freed. Partition invalidation and deletion may take more than 10secs during which SDCC controller can suspend due to runtime pm functionality. Once the block layer activity is done it claims host to detach card from MMC bus which triggers SDCC resume. As the host->card is NULL already there is a BUG_ON hit in mmc_sd_resume(). Fix this by claiming host even before we free host->card.
