[PATCH] fscrypt: rename fscrypt_info => fscrypt_inode_info

[Eric Biggers <ebiggers@kernel.org>]

From: Josef Bacik <josef@toxicpanda.com>

We are going to track per-extent information, so it'll be necessary to
distinguish between inode infos and extent infos.  Rename fscrypt_info
to fscrypt_inode_info, adjusting any lines that now exceed 80
characters.

[ebiggers: renamed fscrypt_get_info(), adjusted two comments, and fixed
 some lines over 80 characters]
