The original code had calls to snprintf(p, 7, "wpa_ie=") but that string
is 8 characters (because snprintf() puts a NUL terminator on the end).
So instead of an '=' the what gets written to buf is a NUL terminator
followed by the rest of the string.

And actually the %02x formats are three chars as well when you include
the terminator.

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.

Currently zram will do nothing to the page in the bvec when that page
has not been previously written.  This allows random data to leak to
user space.  That can be seen by doing the following:

 ## Load the module and create a 256Mb zram device called /dev/zram0
 # modprobe zram
 # echo $((256*1024*1024)) > /sys/class/block/zram0/disksize

 ## Initialize the device by writing zero to the first block
 # dd if=/dev/zero of=/dev/zram0 bs=512 count=1

 ## Read ~256Mb of memory into a file and hope for something interesting
 # dd if=/dev/zram0 of=file

This patch will treat an unwritten page as a zero-filled page.  If a
page is read before a write has occurred the data returned is all 0's.

This change is in a conditional block which is entered only when there is
an existing data block on the freelist where the insert has taken place.

The new block is pushed onto the freelist stack and this conditional block
is updating links in the prior stack head to point to the new stack head.
After this conditional block the first-/second-level indices are updated
to indicate that there is a free block at this location.

This patch adds an immediate return from the conditional block to avoid
setting bits again to indicate a free block on this freelist. The bits
would already be set because there was an existing free block on this
freelist.
