Vignesh Viswanathan 9db31edf92 remoteproc: qcom_q6v5_pas: Fix error masking in qcom_pas_stop() 
In qcom_pas_stop function, return value of qcom_pas_shutdown for pas_id
is overwritten by the return value of qcom_pas_shutdown for dtb_pas_id.
This causes errors seen on qcom_pas_shutdown failures for pas_id to be
masked to the caller. This might lead to issues where the memory regions
locked by PAS, as part of qcom_pas_auth_and_reset, are not released for
access by linux and rproc_coredump flow will end up accessing the locked
memory, leading to an access violation.

Fix this by using a separate variable for the dtb_pas_id shutdown call
and only overriding the main return value if the pas_id shutdown succeeded
but dtb_pas_id shutdown failed.

Fixes: 29814986b8 ("remoteproc: qcom_q6v5_pas: add support for dtb co-firmware loading")
