[PATCH v2] accel/qaic: Fix slicing memory leak

From: Jeffrey Hugo
Date: Wed Aug 02 2023 - 11:00:14 EST


From: Pranjal Ramajor Asha Kanojiya <quic_pkanojiy@xxxxxxxxxxx>

The temporary buffer storing slicing configuration data from user is only
freed on error. This is a memory leak. Free the buffer unconditionally.
