[BUG] Fix from #17770 breaks compiling with AUTO_BED_LEVELING_BILINEAR

[Masanetz]

The fix from #17770 seems to break compiling with AUTO_BED_LEVELING_BILINEAR, as abl_points nether declared nor has it a value...
Maybe the comment in line 248 of G29.cpp is somewhat misleading:
#elif ENABLED(PROBE_MANUALLY) // Bilinear
changed to
#elif EITHER(PROBE_MANUALLY, AUTO_BED_LEVELING_BILINEAR) // Bilinear
it compiled again...

I did a different fix to get it to compile. I replaced "abl_points" to "int(GRID_MAX_POINTS)" on line 646

[RemcoPerlee]

I was using the file that is currently on GitHub (checked just a sec ago)

[ellensp]

That is latest bugfix. It got broken 4 hours ago on bugfix only. ea520e6

Bug confirmed.

Thanks for this post, was going insane. I can compile fine without AUTO_BED_LEVELING_BILINEAR,
SKR mini e3 2. Is there any 'fix' we can do ourselves for this please?

Edit: Thanks to someone in the fix note; (NAPCAL)

Only for debugging adding this code at the blank line (234) int constexpr abl_points = GRID_MAX_POINTS; // ADDED FOR DEBUG TAW
and the error doesn't show and fully compiles.

(234) int constexpr abl_points = GRID_MAX_POINTS; // ADDED FOR DEBUG TAW

With this fix, it compiles for me.
(Without the fix)

[qwewer0]

Fixed with #18552

[sjasonsmith]

I can confirm that it is now fixed for me as well.
