Add missing idr_destroy() call in vduse_exit() to properly free the
vduse_idr radix tree nodes. Without this, module load/unload cycles leak
576-byte radix tree node allocations, detectable by kmemleak as:
unreferenced object (size 576):
backtrace:
[<ffffffff81234567>] radix_tree_node_alloc+0xa0/0xf0
[<ffffffff81234568>] idr_get_free+0x128/0x280
The vduse_idr is initialized via DEFINE_IDR() at line 136 and used throughout
the VDUSE (vDPA Device in Userspace) driver for device ID management. The fix
follows the documented pattern in lib/idr.c and matches the cleanup approach
used by other drivers.
This leak was discovered through comprehensive module testing with cumulative
kmemleak detection across 10 load/unload iterations per module.
