[pve-devel] [PATCH qemu-server 2/4] migration: drop removed 'compress' capability

[Fiona Ebner]

This was added by commit b62532e4 ("migration: disable compress")
stating:

> it's already disable by default,
> but we want to be sure if it's change in later release

QEMU never did change the default (verified with QEMU 8.0 and that
would be would've been a breaking change from QEMU's side).

The 'compress' capability was removed in QEMU 9.1, with QEMU commit
0222111a22 ("migration: Remove non-multifd compression").

The function to set migration capabilities already queries which ones
are supported by the currently running QEMU and ignores others, so
there was no error about 'compress'.
