Prateek Sood cc283bfae1 firmware_loader: fix memory leak for paged buffer ...

commit 4965b8cd1b upstream.

vfree() is being called on paged buffer allocated
using alloc_page() and mapped using vmap().

Freeing of pages in vfree() relies on nr_pages of
struct vm_struct. vmap() does not update nr_pages.
It can lead to memory leaks.

Fixes: ddaf29fd9b ("firmware: Free temporary page table after vmapping")
