Series usb: rework usb_maxpacket() and remove its third argument | expand

Commit Message

Vincent MAILHOL March 16, 2022, 4:19 p.m. UTC 
The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).

N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.
