    bpf: Do cleanup in bpf_bprintf_cleanup only when needed
    
    Currently we always cleanup/decrement bpf_bprintf_nest_level variable
    in bpf_bprintf_cleanup if it's > 0.
    
    There's possible scenario where this could cause a problem, when
    bpf_bprintf_prepare does not get bin_args buffer (because num_args is 0)
    and following bpf_bprintf_cleanup call decrements bpf_bprintf_nest_level
    variable, like:
    
      in task context:
        bpf_bprintf_prepare(num_args != 0) increments 'bpf_bprintf_nest_level = 1'
        -> first irq :
           bpf_bprintf_prepare(num_args == 0)
           bpf_bprintf_cleanup decrements 'bpf_bprintf_nest_level = 0'
        -> second irq:
           bpf_bprintf_prepare(num_args != 0) bpf_bprintf_nest_level = 1
           gets same buffer as task context above
    
    Adding check to bpf_bprintf_cleanup and doing the real cleanup only if we
    got bin_args data in the first place.
