rbd: replace usage of found with dedicated list iterator variable

Browse Source 
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean.

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.
