[PATCH 4/7] media: mediatek: vcodec: simplify cleanup using __free

[Sanjay Chitroda <sanjayembeddedse@gmail.com>]

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

Replace manual cleanup logic with __free attribute from cleanup.h. This
removes explicit kfree() calls and simplifies the error handling paths.

No functional change intended for kmalloc().
