crypto: ccp - Make ccp_dev_suspend and ccp_dev_resume void functions 

Since ccp_dev_suspend() and ccp_dev_resume() only return 0 which causes
ret to equal 0 in sp_suspend and sp_resume, making the if condition
impossible to use. it might be a more appropriate fix to have these be
void functions and eliminate the if condition in sp_suspend() and
sp_resume().
