usb: gsi: Allocate strings IDs for functions on every bind

Currently gsi driver calling usb_string_id() from bind() callbacks
to allocate string IDs for functions and then store that ID in the
appropriate descriptors and string table. This string_id will cleared
from composite driver in unbind path. During composition switch when
bind happens its checking previously allocated string_id for functions
and doesn't allocating again a new staring_id.

This will cause incorrect string_id assignment to usb functions and
USB CV interface descriptor test failing with no strings for
some compositions.

Hence fix this issue by allocating string_ids upon every function bind.
