[PATCH] net/cpfl: fix build error for debian 32-bit

[Bruce Richardson]

When building for debian 11 32-bit, errors were reported with cpfl
driver[1]. The error is due to comparing signed and unsigned values:

../drivers/net/cpfl/cpfl_flow_parser.c:1699:29: error: comparison of
  integer expressions of different signedness: 'long int' and
  'uint32_t' {aka 'unsigned int'} [-Werror=sign-compare]

Fix the issue by using an explicitly cast for the return value from
atol.

Fixes: c10881d3ee74 ("net/cpfl: support flow prog action")
