tools: fdtgrep: Fix handle leak
The handle "fd" was created in fdtgrep.c:708 by calling the
"open" function and is lost in fdtgrep.c:716 and fdtgrep.c:723.
Close file descriptor 'fd' before exiting with an error from function
utilfdt_read_err_len(const char *filename, char **buffp, off_t *len).
Fixes: 1043d0a0296a ("fdt: Add fdtgrep tool")
