[PATCH] fscrypt: drop obsolete recommendation to enable optimized SHA-512

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

Since the crypto kconfig options are being fixed to enable optimized
SHA-512 automatically
(https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/),
it is no longer necessary to give a recommendation to enable it.

 Contents encryption
 -------------------
 
 For contents encryption, each file's contents is divided into "data
 units".  Each data unit is encrypted independently.  The IV for each
