[07/17] wispr: Add and leverage 'cancel_connman_wispr_portal_context'.

Commit Message

Grant Erickson Nov. 16, 2023, 1:02 a.m. UTC

This factors out from 'free_connman_wispr_portal_context', adds, and
leverages as an independent, file-scoped function
'cancel_connman_wispr_portal_context'. It attempts to cancel any
outstanding WISPr request associated with the specified WISPr/portal
context, deallocating any resources associated with the context,
except for the context itself which still requires invoking
'free_connman_wispr_portal_context'.
