When CFQ calls wbt_disable_default(), it will call
blk_stat_remove_callback() to stop gathering IO statistics for the
purposes of writeback throttling. Later, when request_queue is
unregistered, wbt_exit() will call blk_stat_remove_callback() again
which will try to delete callback from the list again and possibly cause
list corruption.
Fix the problem by making wbt_disable_default() called wbt_exit() which
is properly guarded against being called multiple times.

Multi-way decision contains two anomalies.

of a struct member. This local variable is used as the conditional to
the multi-way decision. This is unnecessary, the same logic can be
expressed using the struct member directly.
Secondly, there are four branches in the multi-way decision, two of
which can never be executed. This is dead code.

Function has duplicate code clean up sequences; identical function
call followed by return. This would be better expressed with the use
of a goto statement, as is typical in-tree.
One call site places the clean up code within the 'else' branch of an
multi-way decision. This can be more clearly expressed by inverting
the initial decision conditional and jumping directly to the cleanup
code. Subsequent code indentation can then be reduced, aiding
readability.

This change will mean a number of whitespace issues need to be
addressed/fixed. The diff can be a little hard to read when there are
multiple lines that are very similar (for example error return
code). Splitting the indentation reduction and the whitespace fixes
into two separate patches was not found to aid reading the
