[PATCH] fs/resctrl: Optimize code in rdt_get_tree()

[Shaopeng Tan <tan.shaopeng@jp.fujitsu.com>]

schemata_list_destroy() has to be called if schemata_list_create() fails.

rdt_get_tree() calls schemata_list_destroy() in two different ways:
directly if schemata_list_create() itself fails and
on the exit path via the out_schemata_free goto label.

Remove schemata_list_destroy() call on schemata_list_create() failure.
Use existing out_schemata_free goto label instead.
