MGS-3083 [#imx-662] fix kernel build error with kasan config

hal/kernel/gc_hal_kernel_command.c: In function gckCOMMAND_Commit:
hal/kernel/gc_hal_kernel_command.c:2718:1:
error: the frame size of 2288 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

removed _commandBufferObject instrance, use kmalloc to avoid kasan error.
