[PATCH] media: videobuf2: move vb2_querybuf() kernel-doc to header

[Tharit Tangkijwanichakul <tharitt97@gmail.com>]

Move the function documentation for vb2_querybuf() from videobuf2-v4l2.c
to videobuf2-v4l2.h to match other functions.

Leaving the comment in the source file prevents the kernel-doc parser
from extracting it - thus become missing from the generated HTML.

Additionally, format the comment block to be the same style as other
functions in the header.
