CVE-2022-50140

In the Linux kernel, the following vulnerability has been resolved: memstick/ms_block: Fix a memory leak 'erased_blocks_bitmap' is never freed. As it is allocated at the same time as 'used_blocks_bitmap', it is likely that it should be freed also at the same time. Add the corresponding bitmap_free() in msb_data_clear().
