drm: Fix comment doc for format_modifiers

Commit Message

The parameter passes an array of uint64_t rather than an array
of structs, but the first words of the comment suggest that it passes
an array of structs - if the reader stops reading at the word "struct".

If the commit is read beyond that point the reader will likely confuse
"drm_format<SPACE>modifiers" with "drm_format<UNDERSCORE>modifiers" and
understand the meaning as "passing an array of elements which are of type
struct drm_format_modifier". That is not correct.

Only if the reader is able to read the comment as
"array of struct drm_format<SPACE>modifiers" will they be close to the
correct meaning. But still not quite there, because the modifiers do not
influence struct drm_format in any way - it is not clear what "a modifier
of a struct" would be.

The comment is changed to simply say that the parameter passes an array of
format modifiers, which is the correct meaning.
