wifi: brcmsmac: ampdu: remove unused cb_del_ampdu_pars struct

struct cb_del_ampdu_pars was added in the initial commit 5b435de0
("net: wireless: add brcm80211 drivers") and its only usage was removed in
commit e041f65d ("brcmsmac: Remove internal tx queue").

Remove the structure definition now. This saves a few lines of code.
