[PATCH V14 01/24] mmc: block: Fix missing blk_put_request()

[Adrian Hunter <adrian.hunter@intel.com>]

Ensure blk_get_request() is paired with blk_put_request().

Fixes: 0493f6fe5bde ("mmc: block: Move boot partition locking into a driver op")
Fixes: 627c3ccfb46a ("mmc: debugfs: Move block debugfs into block module")
