[ Upstream commit 28607b426c3d050714f250d0faeb99d2e9106e90 ]
For all but one error path clk_disable_unprepare() is already there. Add
it to the one location where it's missing.
Fixes: 481815a6193b ("mtd: st_spi_fsm: Handle clk_prepare_enable/clk_disable_unprepare.")
Fixes: 69d5af8d016c ("mtd: st_spi_fsm: Obtain and use EMI clock")
