ANDROID: mmc: move to a SCHED_FIFO thread

(cherry picked from commit 011e507b413393eab8279dac8b778ad9b6e9971b)

Running mmcqd as a prio 120 thread forces it to compete with standard
user processes for IO performance, especially when the system is under
severe CPU load. Move it to a SCHED_FIFO thread to reduce the impact of
load on IO performance.
