firmware_loader: fix memory leak for paged buffer
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: ddaf29fd9bb6 ("firmware: Free temporary page table after vmapping")
