dma-debug: fix memory leak in debug_dma_alloc_coherent
Marty reported a memory leakage introduced by commit 3aaabbf1c39e
("lib/dma-debug.c: fix incorrect pfn calculation"). Fix it
by checking the virtual address before allocating the entry.
This patch also use virt_addr_valid() instead of virt_to_page()
to check if a virtual address is linear.
Fixes: 3aaabbf1 ("lib/dma-debug.c: fix incorrect pfn calculation")
