wifi: cfg80211: add role-based peer limits to FTM capabilities
Peer measurement capabilities currently advertise a single maximum
peer count regardless of device role. Some devices support different
peer limits when operating as initiator versus responder.
Add max_peers fields inside the ftm.ista and ftm.rsta sub-structs of
cfg80211_pmsr_capabilities to allow drivers to advertise per-role peer
limits. These limits are generic and not restricted to any specific
ranging type.
Expose these over nl80211 using new NL80211_PMSR_ATTR_MAX_PEER_ISTA_ROLE
and NL80211_PMSR_ATTR_MAX_PEER_RSTA_ROLE attributes inside the
ISTA_CAPS and RSTA_CAPS nested attributes respectively.
When a role limit is advertised, validate the number of peers in the
request separately for each role using the existing rsta flag in the
FTM request, and reject the request if the limit is exceeded.
