Original commit message:
Fix Bug #54538 - use of exclusive innodb dictionary lock limits performance.
This patch doesn't get rid of the need to acquire the dict_sys->mutex but
reduces the need to keep the mutex locked for the duration of the query
to fsp_get_available_space_in_free_extents() from ha_innobase::info().
This is a port of revno:3548 from the builtin to the plugin.
