Subject: [PATCH] scripts: documentation-file-ref-check: Add line break before exit

If execute ./scripts/documentation-file-ref-check in a directory which is
not a git tree, it will exit without a line break, fix it.

Without this patch:

[loongson@...alhost linux-5.7-rc1]$ ./scripts/documentation-file-ref-check
Warning: can't check if file exists, as this is not a git tree[loongson@...alhost linux-5.7-rc1]$

With this patch:

[loongson@...alhost linux-5.7-rc1]$ ./scripts/documentation-file-ref-check
Warning: can't check if file exists, as this is not a git tree
[loongson@...alhost linux-5.7-rc1]$
