Replace the hand-rolled strsep/strcmp/match_string parsing in
rdmacg_resource_set_max() with a match_table_t and match_token()
pattern, following the convention used by user_proactive_reclaim()
and ioc_cost_model_write().
The old strncmp(value, RDMACG_MAX_STR, strlen(value)) also had two
bugs that are fixed by this refactor:
- It matched "ma" as "max" because strncmp only compared the
shorter strlen(value) bytes.
- It silently accepted "hca_handle=" (empty value) as "max"
because strncmp with n=0 always returns 0.
The match_token() approach also robustly handles extra whitespace in
the input by splitting on " \t\n" and skipping empty tokens.
