We add a new field to struct gfs2_alloc_parms called 'allowed'. gfs2_quota_check() and gfs2_inplace_reserve() return the max blocks allowed by quota and the max blocks allowed by the chosen rgrp respectively in 'allowed'. A new field 'min_target', when non-zero, tells gfs2_quota_check() and gfs2_inplace_reserve() to not return -EDQUOT/-ENOSPC when there are atleast 'min_target' blocks allowable/available. The assumption is that the caller is ok with just 'min_target' blocks and will likely proceed with allocating them.
