slimbus: messaging: Free transaction ID in delayed interrupt scenario

In the Linux kernel, the following vulnerability has been resolved:

slimbus: messaging: Free transaction ID in delayed interrupt scenario

In case of interrupt delay for any reason, slim_do_transfer()
returns timeout error but the transaction ID (TID) is not freed.
This results into invalid memory access inside
qcom_slim_ngd_rx_msgq_cb() due to invalid TID.

Fix the issue by freeing the TID in slim_do_transfer() before
returning timeout error to avoid invalid memory access.
