[SVN commits to the Asterisk project]

New Revision: 433690

Log:
clang compiler warnings: Fix -Wself-assign

Assigning a variable to itself isn't super useful. However, the WAV format
modules make use of this in order to perform byte endian checks. This patch
works around the warning by only performing the self assignment if we are
going to do more than just assign it to ourselves. Which is odd, but true.
