irqchip/riscv-imsic: sync-up state before CPU offline
b98a153 
The "move_prev" pointer in struct imsic_vector on the new CPU is
cleared only after the old CPU has cleared "move_next". But when
migrating all the interrupts out from an offling CPU, since the CPU
is already marked as "offlined", the IMSIC driver skip to sync-up the
interrupt vector in __imsic_remote_sync(). The "move_prev" pointer of
these interrupts can only be cleared after the old CPU backs to online.
Therefore, the affinity of interrupts originally targeting an offlined
CPU cannot be updated.

Clear the "move_prev" pointers in the CPU hotplug offline path to avoid
stale migration state on offlined CPUs.

Fixes: 0f67911 ("irqchip/riscv-imsic: Separate next and previous pointers in IMSIC vector")
