dsp-kernel: Handle spin lock in error scenarios

Currently, the code flow bails out without releasing the spin lock,
leading to spin lock recursion. Additionally, the free function is
called during this bail, which is a sleep function. To address this
issue, ensure that the spin lock is released before proceeding to the
bail.
