[Bug 1865088] [NEW] setupcon cannot handle large fonts in FONT, "putfont: KDFONTOP: Invalid argument"

[Ben Harris]

Public bug reported:

When I specify a large font file using the FONT variable in .console-
setup, setupcon fails to load the font, reporting "putfont: KDFONTOP:
Invalid argument".  If I specify the same font by setting CODESET,
FONTFACE, and FONTSIZE, the setupcon loads it fine.

For instance, if I have the following files:

bjh21 at sole:~$ tail .console-setup.test*
==> .console-setup.test1 <==
VERBOSE_OUTPUT="no"
ACTIVE_CONSOLES="/dev/tty[1-6]"
CHARMAP="UTF-8"
CODESET="Uni2"
FONTFACE="Terminus"
FONTSIZE="32x16"

==> .console-setup.test2 <==
VERBOSE_OUTPUT="no"
ACTIVE_CONSOLES="/dev/tty[1-6]"
CHARMAP="UTF-8"
FONT=Uni2-Terminus32x16.psf.gz

==> .console-setup.test3 <==
VERBOSE_OUTPUT="no"
ACTIVE_CONSOLES="/dev/tty[1-6]"
CHARMAP="UTF-8"
FONT=Uni2-Terminus16.psf.gz

Running "setupcon test1" correctly loads Uni2-Terminus32x16, but
"setupcon test2" does not, reporting "putfont: KDFONTOP: Invalid
argument".  "setupcon test3" works, demonstrating that not all uses of
FONT are broken.

I've attached the verbose output from "setupcon -v test2".
