memstick/ms_block: Fix some incorrect memory allocation

Browse source

[ Upstream commit 2e531bc3e0 ]

Some functions of the bitmap API take advantage of the fact that a bitmap
is an array of long.

So, to make sure this assertion is correct, allocate bitmaps with
bitmap_zalloc() instead of kzalloc()+hand-computed number of bytes.

While at it, also use bitmap_free() instead of kfree() to keep the
semantic.
