target/riscv/tcg: restrict satp_mode changes in cpu_set_profile

Browse source 
We're changing 'mmu' to true regardless of whether the profile is
being enabled or not, and at the same time we're changing satp_mode to
profile->enabled.

This will promote a situation where we'll set mmu=on without a virtual
memory mode, which is a mistake.

Only touch 'mmu' and satp_mode if the profile is being enabled.
