EDAC/altera: Fix device node reference leaks in the SDMMC ECC setup
Under altr_portb_setup() and socfpga_init_sdmmc_ecc(),
of_find_compatible_node() was being used to look up the sdmmc-ecc
node. This node wasn't being dropped using of_node_put().
altr_portb_setup() did not drop its reference under its success path
or on any error path.
socfpga_init_sdmmc_ecc() did an early return thereby skipping the
common exit label and thus leaking the reference.
Add the missing of_node_put() calls in altr_portb_setup(), and route
socfpga_init_sdmmc_ecc()'s success path through the common exit label.

Fixes: 788586efd116 ("EDAC/altera: Initialize peripheral FIFOs in probe()")
