Subject: misc: fastrpc: Create fastrpc scalar with correct buffer count
From: Ekansh Gupta <quic_ekangupt@xxxxxxxxxxx>
commit 0b4e32df3e09406b835d8230b9331273f2805058 upstream.
A process can spawn a PD on DSP with some attributes that can be
associated with the PD during spawn and run. The invocation
corresponding to the create request with attributes has total
4 buffers at the DSP side implementation. If this number is not
correct, the invocation is expected to fail on DSP. Added change
to use correct number of buffer count for creating fastrpc scalar.
