[Intel-gfx] [maintainer-tools PATCH 27/30] qf: SC2153 - Fix another shellcheck complain.

[Rodrigo Vivi]

^-- SC2153: Possible misspelling: BASELINE may not be assigned, but baseline is.

BASELINE is defined inside patches/config, but this confuses shellcheck.
According to https://github.com/koalaman/shellcheck/wiki/SC2153
the message doesn't appear for guarded references where if variable
is defined a default is used.

Maybe we should pick a better default like the git HEAD ?!
