Yong-Xuan Wang 5d8622f61e RISC-V: KVM: No need to use mask when hart-index-bit is 0
[ Upstream commit 2d707b4e37 ]

When the maximum hart number within groups is 1, hart-index-bit is set to
0. Consequently, there is no need to restore the hart ID from IMSIC
addresses and hart-index-bit settings. Currently, QEMU and kvmtool do not
pass correct hart-index-bit values when the maximum hart number is a
power of 2, thereby avoiding this issue. Corresponding patches for QEMU
and kvmtool will also be dispatched.
