Bug#1098301: Mpv hardware decoding (vo=gpu) broken on i915 after upgrading Mesa to 24.3

[Nikolas Kyx <knv418@gmail.com>]

It was my problematic /etc/X11/xorg.conf.d/30-igpu.conf
```
Section "Device"
   Identifier  "Intel Graphics"
#   Driver      "intel"
#   Option      "AccelMethod"  "uxa"
   Option      "TearFree" "true"
EndSection
```
Commented out Driver and AccelMethod and it works (either option
breaks hw-accel). WIth old config Xorg.0.log shows:
```
[  1552.904] (II) Initializing extension GLX
[  1552.904] (EE) AIGLX error: dlopen of
/usr/lib/x86_64-linux-gnu/dri/i965_dri.so failed

```
Now it is
```
[  1505.170] (II) Initializing extension GLX
[  1505.182] (II) AIGLX: Loaded and initialized crocus
[  1505.182] (II) GLX: Initialized DRI2 GL provider for screen 0
```

Looks like mesa switched to crocus or something like this. I wonder
how it should be now, but it's not that important and now the issue
can be closed.
