RISC-V: KVM: Drop the _MASK suffix from hgatp.VMID mask defines
The hgatp.VMID mask defines are used before shifting when extracting
VMID value from hgatp CSR value so based on the convention followed
in the other parts of asm/csr.h, the hgatp.VMID mask defines should
not have a _MASK suffix.
While we are here, let's use GENMASK() for hgatp.VMID and hgatp.PPN.
