mtd: st_spi_fsm: Add a clk_disable_unprepare() in .probe()'s error path



[ 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: 481815a6 ("mtd: st_spi_fsm: Handle clk_prepare_enable/clk_disable_unprepare.")
Fixes: 69d5af8d ("mtd: st_spi_fsm: Obtain and use EMI clock")
