Subject: [PATCH 4/6] misc: fastrpc: Fix memory leak in audio daemon attach operation

From: Ekansh Gupta <quic_ekangupt@...cinc.com>

Audio PD daemon send the name as part of the init IOCTL call. This
name needs to be copied to kernel for which memory is allocated.
This memory is never freed which might result in memory leak. Free
the memory when it is not needed.
