[PATCH bpf-next] mm/bpf_memcontrol: Add missing newline in pr_warn message

[Hui Zhu]

From: Hui Zhu <zhuhui@xxxxxxxxxx>

Add missing newline character at the end of pr_warn error message
in bpf_memcontrol_init() function. Kernel log messages should end
with a newline character for proper formatting in kernel logs.

This issue was pointed out in
