mwifiex: sta_cmd: do not enable auto_ds by default

(made based on commit https://github.com/sebanc/linux-kernel/commit/5cd03f3e1c01440d0e0bd0cd00a51732c07f99da)

According to the commit this commit is based on, enabling "auto deep
sleep" (auto_ds) causes "suspend/resume fails when not connected to
an Access Point.".

This commit stops enabling auto_ds on driver initialization to fix the
issue.
