[SCSI] i2o: fix memory leak in i2o_exec_lct_modified
i2o_exec_lct_modified() does not release memory allocated for work_struct. Signed-off-by: Vasily Averin <vvs@sw.ru> Although your patch is the same, i've rewritten it a little bit for naming consistency in the I2O driver. Acked-by: Markus Lidel <Markus.Lidel@shadowconnect.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
