kernel: Determine kernel vs. user page fault depending on iframe.
The action vm_page_fault takes should depend on whether the iframe to be
handled is a user iframe or not. The check for the user flag in the
error code does however only check if the fault happend in user or
kernel space. Use IFRAME_IS_USER() instead which checks the privilege
level of the iframe. Under 32 bit x86 this also handles vm86
compatibility mode properly.
This is the same logic as used on FreeBSD (TRAPF_USERMODE).
Fixes #13930.
