Mohammed Naser 6b86391bb2 rbd: Backout if image features is empty
In golang world, if you split an empty string that does not contain
the seperator, you get an array with one empty string.  This results
in volumes failing to mount with "invalid feature " (note extra space
because it's trying to check if 'empty string' is a valid feature).

This patch checks if the string is empty, and if so, it just decides
to skip the entire validation and returning nothing.
