RISC-V: KVM: Write hgatp register with valid mode bits
f9ad50e 
According to the RISC-V Privileged Architecture Spec, when MODE=Bare
is selected,software must write zero to the remaining fields of hgatp.

We have detected the valid mode supported by the HW before, So using a
valid mode to detect how many vmid bits are supported.

RISC-V KVM: Remove unnecessary HGATP csr_read
eda996c 
The HGATP has been set to zero in gstage_mode_detect(), so there
is no need to save the old context. Unify the code convention
with gstage_mode_detect().
