mmc: core: Retry claim host in mmc_sd_detect
Use mmc_try_claim_host with a timeout instead of mmc_claim_host in
mmc_sd_detect. This is to ensure that mmc rescan work item is doesn't
get blocked on claim_host for longer period.
In the pm_suspend path, we cancel the mmc_rescan work item.
If this work item is already scheduled, suspend would be blocked till
mmc_rescan gets finished. In case, mmc_rescan is blocked on claim_host
lock, pm_suspend could get blocked for longer period. This can result
in momentary UI freeze since pm_suspend is blocked for longer duration.
This change is to prevent this scenario.
