xend: On block-attach, remove device information when VmError occurs.

I tested xm block-attach command with a wrong
parameter(file:). Naturally a command error occurred. Then I retested
xm block-attach command with a correct parameter(phy:). But a command
error occurred again. The second command error occurred because Xend
did not remove device information from self.info when the first
command error occurred.
