firmware_class: fix memory leak - free allocated pages
fix memory leak introduced by the patch 6e03a201bbe:
firmware: speed up request_firmware()
1. vfree won't release pages there were allocated explicitly and mapped
using vmap. The memory has to be vunmap-ed and the pages needs
to be freed explicitly
2. page array is moved into the 'struct
firmware' so that we can free it from release_firmware()
and not only in fw_dev_release()
The fix doesn't break the firmware load speed.
