sparc: fix size argument to find_next_zero_bit()
iommu_alloc_ctx() finds a zero bit in iommu->ctx_bitmap. It starts
searching from iommu->ctx_lowest_free to the end of the bitmap.
But the size argument to find_next_zero_bit() in iommu_alloc_ctx()
is wrong. It should be the bitmap size, not the maximum size to
search from the offset argument.
Fortunately iommu->ctx_lowest_free is almost unused and it will not
be more than 1. So the bug wasted only 1-bit at the end of
iommu->ctx_bitmap.
