[SCSI] dpt_i2o: Use GFP_ATOMIC when a lock is held
The function adpt_i2o_post_wait is called from several places, in some of
which, such as adpt_abort, a lock may be held.
The functions adpt_i2o_reparse_lct and adpt_i2o_lct_get are called from
several places, including adpt_rescan where a lock may be held.
The semantic patch that makes this change is as follows:
