[PATCH 4.19/5.4/5.10 0/1] gfs2: Always check inode size of inline inodes

[Fedor Pchelkin <pchelkin@xxxxxxxxx>]

Kernel bug in iomap_read_inline_data() fixed by the following patch is hit
on older stables 4.19/5.4/5.10.

The patch failed to be initially backported into stable branches older
than 5.15 due to the upstream commit 7db354444ad8 ("gfs2: Cosmetic
gfs2_dinode_{in,out} cleanup").

Now it can be cleanly applied to the 4.19/5.4/5.10 stable branches.
