From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit a6f8e68e238a15bb15f1726b35c695136c64eaba ]

If an error occurs after calling 'sp_get_irqs()', 'sp_free_irqs()' must be
called as already done in the error handling path.

Fixes: f4d18d656f88 ("crypto: ccp - Abstract interrupt registeration")
