Cleanup code style issue reported by kernel checkpatch. As follows:
  * ERROR:CODE_INDENT: code indent should use tabs where possible
  * ERROR:SPACING: spaces required around that '?' (ctx:VxE)
  * WARNING:INDENTED_LABEL: labels should not be indented

Fixes: b0489e7bca2f ("malloc: fix linear complexity")
Cc: stable@dpdk.org

Here and below, I believe we usually add two indents to the continuation 
line, to avoid confusing with things like if statements.

It is already two indents in the patch. Please double check?

No it is two indents from the beginning of the line,
while Anatoly was asking for double additional indent.

I fix it.
