Andy Shevchenko 2305e3460b vsprintf: Fix potential unaligned access 
[ Upstream commit d75b26f880 ]

The %p4cc specifier in some cases might get an unaligned pointer.
Due to this we need to make copy to local variable once to avoid
potential crashes on some architectures due to improper access.

Fixes: af612e43de ("lib/vsprintf: Add support for printing V4L2 and DRM fourccs")
