[PATCH v4 1/4] xfs: set minleft correctly for sparse chunk errortag allocation

[Brian Foster <bfoster@redhat.com>]

The errortag instrumentation for forced sparse chunk allocation
jumps straight to the allocation path without setting args.minleft.
minleft is unconditionally set to ->inobt_maxlevels for the normal
allocation path. Lift the assignment to the initial args setup so
it covers all possible paths.
