[PATCH v2 1/2] libcamera: formats: Silence warning when creating a PixelFormatInfo from a null format

[Stefan Klug]

Calling PixelFormat().toString() correctly returns "0x0-<INVALID>" but it
also produces the following, possibly confusing, warning:

WARN Formats formats.cpp:1006 Unsupported pixel format 0x00000000

Silence the warning in PixelFormatInfo::info() in case the format is
invalid.
