x86/shadow: More consistent printing for debug messages
* Use %pv or just d%d in preference to the multiple current ways of
presenting the same information.
* Use PRI_mfn instead of opencoding it.
* Drop all explicit use of __func__ from SHADOW_{PRINTK,DEBUG}() calls.
The
wrappers already include it.
* Use hex rather than decimal for printing a pagefault error code.
