media: atomisp: fix uninitialized stack mem usage in ia_css_rmgr_acq_vbuf()

Browse source

When ia_css_rmgr_acq_vbuf() enters the code path where it uses the local
"struct ia_css_rmgr_vbuf_handle v" on the stack it relies on v.count==0
so that ia_css_rmgr_refcount_retain_vbuf allocates a new handle.

Explicitly set v.count to 0 rather then it being whatever was on the stack.
