    selftests/net: ipsec: fix constant out of range
    
    [ Upstream commit 088559815477c6f623a5db5993491ddd7facbec7 ]
    
    Fix a small compiler warning.
    
    nr_process must be a signed long: it is assigned a signed long by
    strtol() and is compared against LONG_MIN and LONG_MAX.
    
    ipsec.c:2280:65:
        error: result of comparison of constant -9223372036854775808
        with expression of type 'unsigned int' is always false
        [-Werror,-Wtautological-constant-out-of-range-compare]
    
      if ((errno == ERANGE && (nr_process == LONG_MAX || nr_process == LONG_MIN))
