setup_file_encryption_key() is doing a lot of things at the moment --
setting the crypt_info's inline encryption bit, finding and locking a
master key, and calling the functions to get the appropriate prepared
key for this info. Since setting the inline encryption bit has nothing
to do with finding the master key, it's easy and hopefully clearer to
select the encryption implementation in fscrypt_setup_encryption_info(),
the main fscrypt_info setup function, instead of in
setup_file_encryption_key() which will long-term only deal in setting
up the prepared key for the info.
