Eric Biggers a4d14e915b fscrypt: improve warnings for missing crypto API support ...

Users of fscrypt with non-default algorithms will encounter an error
like the following if they fail to include the needed algorithms into
the crypto API when configuring the kernel (as per the documentation):

    Error allocating 'adiantum(xchacha12,aes)' transform: -2

This requires that the user figure out what the "-2" error means.
Make it more friendly by printing a warning like the following instead:

    Missing crypto API support for Adiantum (API name: "adiantum(xchacha12,aes)")

Also upgrade the log level for *other* errors to KERN_ERR.
