Log:
MFC r266426
Slightly restructure the final loop in rman_reserve_resource_bound().
Replace with the existing loop termination test with a similar
condition from the nested "if" that may terminate the loop a bit
sooner, but still not too early. This condition can then be removed
from the nested "if". Relocate an operator to be style(9) compliant.
