qcacld-3.0: Cleanup residual debug guarding

This reverts commit 8da490f ("qcacld-3.0: Enable debugfs usage")

This just simply isn't necessary, we don't use debugfs, and my
initial cautious reasoning for allowing qcacld to utilize it
(custom ROM libperfmgr implementations) never came to be, and never
will at this juncture.

This partially reverts commit 21b2cbe (""qcacld-3.0: Do not compile logging")

While most of this patch will remain intact, subsequent to 0e74ab4
("qcacld-3.0: Merge tag 'LA.UM.9.12.r1-08400-SMxx50.0' into
neutrino-msm-hotdogb-4.14"), wlan_hdd_print_suspend_fail_stats is no longer
guarded by WLAN_DEBUG so drop the trailing #endif relocated by this commit.
