[Pdbg] [PATCH] debug: Add printf attribute to logging function

[Joel Stanley]

This allows the compiler to warn about mismatched types in printf
arguments.

Without this we don't get warnings from the logging macros when format
specifiers and arguments don't match up, and instead you get segfaults.
