selftests/net: ipsec: fix constant out of range

Browse Source 
[ 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))
