crypto: hisilicon/zip - remove unnecessary validation for high-performance mode confi...

[ Upstream commit d4e081510471e79171c4e0a11f6cb608e49bc082 ]

When configuring the high-performance mode register, there is no
need to verify whether the register has been successfully
enabled, as there is no possibility of a write failure for this
register.
