Revert "irqchip/riscv-imsic: Embed the vector array in lpriv"
The __alloc_percpu() fails when the number of IDs are greater than 959
because size parameter of __alloc_percpu() must be less than 32768 (aka
PCPU_MIN_UNIT_SIZE). This failure is observed with KVMTOOL when AIA is
trap-n-emulated by in-kernel KVM because in this case KVM guest has 2047
interrupt IDs.
To address this issue, don't embed vector array in struct imsic_local_priv
until __alloc_percpu() support size parameter greater than 32768.
This reverts commit 79eaabc61dfb ("irqchip/riscv-imsic: Embed the vector
array in lpriv").
