wifi: cfg80211: guard optional PMSR nominal time

pmsr_parse_ftm() rejects a request that omits NOMINAL_TIME only for
non-trigger-based PD ranging. It then reads the attribute
unconditionally for every non-trigger-based request:

	out->ftm.nominal_time =
		nla_get_u32(tb[NL80211_PMSR_FTM_REQ_ATTR_NOMINAL_TIME]);

For the other non-trigger-based request types NOMINAL_TIME is optional,
so tb[...] can be NULL and nla_get_u32() dereferences a NULL pointer.

Keep the requirement for PD ranging and read the nominal-time value only
when the attribute is present.
