Subject: [PATCH 3.8 21/81] rtlwifi: Fix incorrect return from rtl_ps_enable_nic()

3.8.13.20 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Olivier Langlois <olivier@...llion01.com>

commit 2e8c5e56b307271c2dab6f8bfd1d8a3822ca2390 upstream.

rtl_ps_enable_nic() is called from loops that will loop until this function returns true or a
maximum number of retries is performed.

hw_init() returns non-zero on error. In that situation return false to
restore the original design intent to retry hw init when it fails.
