ARM: at91: pm: add missing put_device() call in at91_pm_sram_init()
[ Upstream commit f87a4f022c44e5b87e842a9f3e644fba87e8385f ]
if of_find_device_by_node() succeed, at91_pm_sram_init() doesn't have
a corresponding put_device(). Thus add a jump target to fix the exception
handling for this function implementation.
Fixes: d2e467905596 ("ARM: at91: pm: use the mmio-sram pool to access SRAM")
