Protects mapping and unmapping of data buffers as well as structures using mutex
bug 2174390

1. This will protect buffers from getting unmapped from one thread while other thread is mapping them.
2. It will also protect strmctrl & algctrl related structures from getting unmapped while other thread is using them for sending message
to DSP.
This is a partial solution for testVideoCapture failures. Refer to CSR# OMAPS00207906.
Incorporates fixes for review comments made by Dave Sparks.
This patch replaces the original patch #1287.
