malloc: fix style in free list index computation

[ upstream commit a99d252 ]

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: b0489e7 ("malloc: fix linear complexity")
