[PATCH] powerpc/mm/radix: add missing braces for single statement block

[Mathieu Malaterre]

In commit 7a22d6321c3d ("powerpc/mm/radix: Update command line parsing for
disable_radix") an `if` statement was added for a possible empty body
(prom_debug).

Fix the following warning, treated as error with W=1:

  arch/powerpc/kernel/prom_init.c:656:46: error: suggest braces around empty 
body in an ‘if’ statement [-Werror=empty-body]
