scsi: ipr: Fix incorrect function names in their headers

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/ipr.c:5335: warning: expecting prototype for ipr_eh_dev_reset(). Prototype was for __ipr_eh_dev_reset() instead
 drivers/scsi/ipr.c:5594: warning: expecting prototype for ipr_eh_abort(). Prototype was for ipr_scan_finished() instead
 drivers/scsi/ipr.c:5616: warning: expecting prototype for ipr_eh_host_reset(). Prototype was for ipr_eh_abort() instead
 drivers/scsi/ipr.c:6725: warning: expecting prototype for ipr_info(). Prototype was for ipr_ioa_info() instead

[mkp: tweaked ipr_scan_finished() comment]
