docs: Remove references to invalid error APIs

Following APIs have been replaced with more generic cephError type to
jointly indicate the source and error.

cephFSError.Error
cephFSError.ErrorCode
radosError.Error
radosError.ErrorCode
rbdError.Error
rbdError.ErrorCode

Therefore remove corresponding entries from API docs.
