Fangyu Yu 1fa7e6e78b RISC-V: KVM: Fix guest page fault within HLV* instructions 
[ Upstream commit 974555d6e4 ]

When executing HLV* instructions at the HS mode, a guest page fault
may occur when a g-stage page table migration between triggering the
virtual instruction exception and executing the HLV* instruction.

This may be a corner case, and one simpler way to handle this is to
re-execute the instruction where the virtual  instruction exception
occurred, and the guest page fault will be automatically handled.
