daemon: replace ErrVolumeReadonly with errdefs
It was only used in a single location, and the ErrVolumeReadonly was not checked
for, or used as a sentinel error.

This error was introduced in c32dde5baa. It was
never used as a sentinel error, but from that commit, it looks like it was added
as a package variable to mirror already existing errors defined at the package
level.

This patch removes the exported variable, and replaces the error with an
errdefs.InvalidParameter(), so that the API also returns the correct (400)
status code.
