fs: remove inode::i_verity_info
Now that all fsverity-capable filesystems store the pointer to
fsverity_info in the filesystem-specific part of the inode structure,
inode::i_verity_info is no longer needed. Update fsverity_info_addr()
to no longer support the fallback to inode::i_verity_info. Finally,
remove inode::i_verity_info itself, and move the forward declaration of
struct fsverity_info from fs.h (which no longer needs it) to fsverity.h.
The end result of the migration to the filesystem-specific pointer is
memory savings on CONFIG_FS_VERITY=y kernels for all filesystems that
don't support fsverity. Specifically, their in-memory inodes are now
smaller by the size of a pointer: either 4 or 8 bytes.
