wifi: mac80211: fix macro scoping in for_each_link_data

The for_each_link_data() macro currently declares a local variable
__sdata directly, which could lead to compiler warnings or errors when
reused in the same function or within switch-case blocks due to variable
redefinition or invalid scoping.

To address this, restructure the macro to use an outer for-loop that runs
only once, allowing safe declaration of __sdata without polluting the outer
scope. This ensures compatibility with static analyzers.

No functional changes; this is purely a cleanup to improve macro hygiene.
