spi: stm32-qspi: remove signal sensitive on completion
On umount step a sigkill signal is set (without user specific action), due to sigkill signal the completion will be interrupted and the data transfer can't be finished if a sync is needed. Signed-off-by: Ludovic Barre <ludovic.barre@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
