[PATCH 6.18.y, 6.12.y, 6.6.y] media: rc: ttusbir: fix inverted error logic

[Jan Kiszka]

From: Oliver Neukum <oneukum@suse.com>

[ Upstream commit 646ebdd3105809d84ed04aa9e92e47e89cc44502 ]

We have to report ENOMEM if no buffer is allocated.
Typo dropped a "!". Restore it.

Fixes: 50acaad3d202 ("media: rc: ttusbir: respect DMA coherency rules")

Unclear why this failed during auto-backport because it applied 
perfectly to the affected stable kernels. Just 7.0.y truly fails because 
it does not carry the buggy patch 50acaad3d202.
