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.
