Function show_mem() is used to print system memory status when user

early initialization) should be tolerable and the worst that could
happen is to print an imprecise node state.
Drop the resize lock because this is the only place which might hold
the
lock from the interrupt context and so all other callers might use a
simple spinlock. Even though this doesn't solve any real issue it makes
the code easier to follow and tiny more effective.
