Add maxframerate field as part of pixelformat

Inserting new pages in a handle to a vma does not seem
to improve perf in most cases and so is more like overhead.
Remove this path. Accounting dirty pages should not hold
handle lock again from within nvmap_handle_mk(), so add
an argument to it to avoid taking the lock again from
_nvmap_handle_mkdirty().
When handle has all clean pages, avoid any further clean operation.
Similarly for dirty pages. This avoids any unnecessary overeheads
in empty cuda kernel launch whose buffer is not accessed by cpu
before passing to GPU.
