Zach Brown 44a7e2ab56 scoutfs: more carefully handle alloc cursors ...

The first pass at the radix allocator wasn't paying a lot of attention
to the allocation cursors.

This more carefully manages them.  They're only advanced after
allocating.  Previously the metadata alloc cursor was advanced as it
searched through leaves that it might allocate from.  We test for
wrapping past the specific final allocatable bit, rather than the limit
of what the radix height can store.  This required pushing knoweldge of
metadata or data allocs down through some of the code paths.
