target/riscv: log guest errors when reserved bits are set in PTEs
For instance, QEMUs newer than b6ecc63c569bb88c0fcadf79fb92bf4b88aefea8
would silently treat this akin to an unmapped page (as required by the
RISC-V spec, admittedly). However, not all hardware platforms do (e.g.
CVA6) which leads to an apparent QEMU bug.
Instead, log a guest error so that in future, incorrectly set up page
tables can be debugged without bisecting QEMU.
