x86/kexec: use pr_err() instead of kexec_dprintk() when an error occurs
When detecting an error, the current code uses kexec_dprintk() to output
log message. This is not quite appropriate as kexec_dprintk() is mainly
used for outputting debugging messages, rather than error messages.
Replace kexec_dprintk() with pr_err(). This also makes the output method
for this error log align with the output method for other error logs in
this function.
Additionally, the last return statement in set_page_address() is
unnecessary, remove it.
