soundwire: qcom: move sconfig in qcom_swrm_stream_alloc_ports() out of critical section

Browse source 
Setting members of local variable "sconfig" in
qcom_swrm_stream_alloc_ports() does not depend on any earlier code in
this function, so can be moved up before the critical section.  This
makes the code a bit easier to follow because critical section is
smaller.
