[PATCH 1/2] qed: Use the bitmap API to allocate bitmaps

[PATCH 1/2] qed: Use the bitmap API to allocate bitmaps

[Christophe JAILLET]

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.

It is less verbose and it improves the semantic.

[PATCH 2/2] qed: Use bitmap_empty()

[Christophe JAILLET]

Use bitmap_empty() instead of hand-writing it.
