It seems to be related to changes in uvm_loan.c
as uvm_loan() is now able to return with uobj/anon locked as we might get a
return value of 0 from uvm_loanentry. That might happen if uvm_loanentry
returns while in the first iteration of the while loop with rv == 0
Am not sure but it does not look right the way it is....
