drm/amdgpu: fix uninitialized variable pasid_mapping_needed

Browse Source 
[ Upstream commit 17cf678a33 ]

The boolean variable pasid_mapping_needed is not initialized and
there are code paths that do not assign it any value before it is
is read later.  Fix this by initializing pasid_mapping_needed to
false.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 6817bf283b ("drm/amdgpu: grab the id mgr lock while accessing passid_mapping")
