fscrypt: replace get_ino_and_lblk_bits with just has_32bit_inodes
Now that fs/crypto/ computes the filesystem's lblk_bits from its maximum
file size, it is no longer necessary for filesystems to provide
lblk_bits via fscrypt_operations::get_ino_and_lblk_bits.
It is still necessary for fs/crypto/ to retrieve ino_bits from the
filesystem. However, this is used only to decide whether inode numbers
fit in 32 bits. Also, ino_bits is static for all relevant filesystems,
i.e. it doesn't depend on the filesystem instance.
Therefore, in the interest of keeping things as simple as possible,
replace 'get_ino_and_lblk_bits' with a flag 'has_32bit_inodes'. This
can always be changed back to a function if a filesystem needs it to be
dynamic, but for now a static flag is all that's needed.
