memory: stm32-fmc2-ebi: add missing of_node_put for loop iteration
Early exits from for_each_available_child_of_node() should decrement the
node reference counter. Reported by Coccinelle:
drivers/memory/stm32-fmc2-ebi.c:1046:1-33: WARNING:
Function "for_each_available_child_of_node" should have of_node_put() before return around line 1051.
Fixes: 66b8173a197f ("memory: stm32-fmc2-ebi: add STM32 FMC2 EBI controller driver")
