fpga: dfl: afu: Corrected error handling levels

Browse source 
[ Upstream commit c9d7e3da1f3c4cf5dddfc5d7ce4d76d013aba1cc ]

Corrected error handling goto sequnece. Level put_pages should
be called when pinned pages >= 0 && pinned != npages. Level
free_pages should be called when pinned pages < 0.
