misc: fastrpc: Fix a possible double free

Browse source

This patch fixes the error exit path of fastrpc_init_create_process().
If the DMA allocation or the DSP invoke fails the fastrpc_map was freed
but not removed from the mapping list leading to a double free once the
mapping list is emptied in fastrpc_device_release().

[srinivas kandagatla]: Cleaned up error path labels and reset init mem
to NULL after free
