[PATCH] drm/amdkfd: Add curly braces around idr_for_each_entry_continue loop

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

The compiler pointed out that one if block unintentionally wasn't part
of the loop:

This is one reason why I think it's better to always use curly braces
around multiple lines, even if it happens to be a single statement.
