migration: equation is more proper than and to check LOADVM_QUIT
LOADVM_QUIT allows a command to quit all layers of nested loadvm loops,
while current return value check is not that proper even it works now.
Current return value check "ret & LOADVM_QUIT" would return true if
bit[0] is 1. This would be true when ret is -1 which is used to indicate
an error of handling a command.
Since there is only one place return LOADVM_QUIT and no other
combination of return value, use "ret == LOADVM_QUIT" would be more
proper.
