boot/fit: print error name in boot_get_fdt_fit()

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.
