Lets remove the member's validity check from sbitmapq_init(), which will
help the crash to display the actual error when the sbitmapq fails.
Without the patch:
crash> sbitmapq ffff8e99d0dc8010
sbitmapq: command not supported or applicable on this architecture or kernel
With the patch:
crash> sbitmapq ffff8e99d0dc8010
sbitmapq: invalid structure member offset: sbitmap_queue_alloc_hint
FILE: sbitmap.c LINE: 365 FUNCTION: sbitmap_queue_context_load()
