Ulf Hansson 3a574919f0 mmc: core: Avoid hanging to claim host for mmc via some nested calls ... As the block layer, since the conversion to blkmq, claims the host using a context, a following nested call to mmc_claim_host(), which isn't using a context, may hang. Calling mmc_interrupt_hpi() and mmc_read_bkops_status() via the mmc block layer, may suffer from this problem, as these functions are calling mmc_claim|release_host(). Let's fix the problem by removing the calls to mmc_claim|release_host() from the above mentioned functions and instead make the callers responsible of claiming/releasing the host. As a matter of fact, the existing callers already deals with it.
