ocfs2: reduce ioctl stack usage

On 32-bit architectures with KASAN_STACK enabled, the total stack usage of
the ocfs2_ioctl function grows beyond the warning limit:

fs/ocfs2/ioctl.c: In function 'ocfs2_ioctl':
fs/ocfs2/ioctl.c:934:1: error: the frame size of 1448 bytes is larger than 1400 bytes [-Werror=frame-larger-than=]

Move each of the variables into a basic block, and mark
ocfs2_info_handle() as noinline_for_stack, in order to have the variable
share stack slots.
