lib: sbi: Fix bug in sbi_ecall_rfence that misses checking
In sbi_ecall_rfence_handler, it will compare the funcid with
REMOTE_HFENCE_GVMA and REMOTE_HFENCE_VVMA_ASID. Later it check
whether the misa includes H-extension. This checking is incomplete
which misses REMOTE_HFENCE_GVMA_VMID and REMOTE_HFENCE_VVMA.
Fix the issue by updating the checking range.
