[U-Boot] [U-BOOT PATCH] sf: Fix sf read for memory-mapped SPI flashes

[Jagannadha Sutradharudu Teki]

Missing return after memcpy is done for memory-mapped SPI flashes,
hence added retun 0 after memcpy done.

The return is missing in below patch
"sf: Enable FDT-based configuration and memory mapping"
