MMU: Fix SDR updates being silently dropped in some cases
While 6xx_pem.pdf §7.6.1.1 mentions that the number of trailing
zeros in HTABORG must be equal to the number of trailing ones
in the mask (i.e. HTABORG must be properly aligned), this is actually
not a hard requirement. Real hardware will just OR the base address
anyway. Ignoring SDR changes would lead to incorrect emulation.

Logging a warning instead of dropping the SDR update silently is a
saner behaviour.
