memstick/ms_block: Fix a memory leak

Browse Source 
[ Upstream commit 54eb7a55be6779c4d0c25eaf5056498a28595049 ]

'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().
