[PATCH 02/62] blk-ioc: Prepare for enabling thread-safety analysis

[Bart Van Assche <bvanassche@acm.org>]

The Clang thread-safety analyzer does not support testing return values
with "< 0". Hence change the "< 0" test into "!= 0". This is fine since
the radix_tree_maybe_preload() return value is <= 0.
