librtas allocates buffer space (required for RTAS call) in the RTAS p…

…rivate

memory area through sc_get_rmo_buffer() which internally allocates memory
and protects it by acquiring lock on the allocated memory area.

Locking function :
   At present acquire_file_lock() tries to lock the particular memory
area. If the memory area is already locked then it returns error without
retrying.

So when two process executes rtas call simultaneously one fails with
"Unknown librtas I/O" error.

This patch introduces "Wait for lock to be available" instead of
returning with IO error.
