Robert Jennings 939b3f0b14 zram/xvmalloc: combine duplicate block delete code ... This patch eliminates duplicate code. The remove_block_head function is a special case of remove_block which can be contained in remove_block without confusion. The portion of code in remove_block_head which was noted as "DEBUG ONLY" is now mandatory. Doing this provides consistent management of the double linked list of blocks under a freelist and makes this consolidation of delete block code safe. The first and last blocks will have NULL pointers in their previous and next page pointers respectively. Additionally, any time a block is removed from a free list the next and previous pointers will be set to NULL to avoid misuse outside xvmalloc.
