Revert "staging: r8712u: Tracking kmemleak false positives."

This reverts commit 5d3da4a20a271e3cf5496a50cbb8118aa019374f.

This commit annotated false positive for kmemleak. The reasoning is that
the buffers are freed when the driver is unloaded. However, there is
actually potential memory leak when probe fails.

staging: r8188eu: fix led register settings

Using an InterTech DMG-02 dongle, the led remains on when the system goes
into standby mode. After wakeup, it's no longer possible to control the
led.

It turned out that the register settings to enable or disable the led were
not correct. They worked for some dongles like the Edimax V2 but not for
others like the InterTech DMG-02.

This patch fixes the register settings. Bit 3 in the led_cfg2 register
controls the led status, bit 5 must always be set to be able to control
the led, bit 6 has no influence on the led. Setting the mac_pinmux_cfg
register is not necessary.

These settings were tested with Edimax V2 and InterTech DMG-02.
