Print the actual error code in a couple of places in boot_get_fdt_fit(). These are FDT error codes, not errno, so printing the string is more helpful than printing the numeric value.
The only caller of boot_get_fdt_fit() unconditionally replaces the returned error code (fdt_noffset) with ENOENT so the actual error would otherwise be lost.
