[Michael Niedermayer]

ffmpeg | branch: release/7.0 | Michael Niedermayer <michael at niedermayer.cc> | Sun May 26 23:34:05 2024 +0200| [0013970c6887abdbcb37a13f1589685264183bd9] | committer: Timo Rothenpieler

qsv: Initialize impl_value

Fixes: The warnings from CID1598553 Uninitialized scalar variable

Passing partly initialized structs is ugly and asking for hard to rieproduce bugs,
The uninitialized fields where not used
