fpga: stratix10-soc: Add missing fpga_mgr_free() call

commit d9ec9daa20eb8de1efe6abae78c9835ec8ed86f9 upstream.

The stratix10-soc driver uses fpga_mgr_create() function and is therefore
responsible to call fpga_mgr_free() to release the class driver resources.
Add a missing call to fpga_mgr_free in the s10_remove() function.
