[PATCH v2] media: usb: fix memory leak in af9005_identify_state

[Navid Emamdoost]

In af9005_identify_state when returning -EIO the allocated buffer should
be released. Replace the "return -EIO" with assignment into ret and move
deb_info() under a check.

Fixes: af4e067e1dcf ("V4L/DVB (5625): Add support for the AF9005 demodulator 
from Afatech")
