Mirsad Goran Todorovac 808ed7d86e test_firmware: fix the memory leak of the allocated firmware buffer 
commit 48e156023059e57a8fc68b498439832f7600ffff upstream.

The following kernel memory leak was noticed after running
tools/testing/selftests/firmware/fw_run_tests.sh:

[root@pc-mtodorov firmware]#

Note that the size 1024 corresponds to the size of the test firmware
buffer. The actual number of the buffers leaked is around 70-110,
depending on the test run.

The cause of the leak is the following:

request_partial_firmware_into_buf() and request_firmware_into_buf()
provided firmware buffer isn't released on release_firmware(), we
have allocated it and we are responsible for deallocating it manually.
This is introduced in a number of context where previously only
release_firmware() was called, which was insufficient.
