soundwire: qcom: Use guard to avoid mixing cleanup and goto

qcom_swrm_stream_alloc_ports() already uses cleanup.h but also has goto.
Such combination is error-prone and discouraged:

"... and that the "goto" statement can jump between scopes, the
expectation is that usage of "goto" and cleanup helpers is never mixed
in the same function."

Actually simplify the code with a guard which allows to fix the
discouraged style by removing the goto.
