etnaviv: fix refcnt initialization in etna_screen

Browse source 
Despite being a member of the etna_screen struct, 'refcnt' is used by
the winsys-specific logic to track the reference count of the object
managed in a hash table. When the count reaches zero, the pipe screen
is removed from the table and destroyed.

Fix the logic by initializing the refcnt to 1 when screen created.
This initialization is done in etna_screen_create(), to follow the
same logic as in freedreno and virgl.
