infiniband: fix ulp/iser/iscsi_iser.h kernel-doc warnings

Fix kernel-doc warnings and typos/spellos.

../drivers/infiniband/ulp/iser/iscsi_iser.h:254: warning: Function parameter or member 'dma_addr' not described in 'iser_tx_desc'
../drivers/infiniband/ulp/iser/iscsi_iser.h:254: warning: Function parameter or member 'cqe' not described in 'iser_tx_desc'

../drivers/infiniband/ulp/iser/iscsi_iser.h:491: warning: Function parameter or member 'snd_w_inv' not described in 'iser_conn'

This leaves 2 "member not described" warnings that I don't know how to fix:

../drivers/infiniband/ulp/iser/iscsi_iser.h:401: warning: Function parameter or member 'all_list' not described in 'iser_fr_desc'
../drivers/infiniband/ulp/iser/iscsi_iser.h:415: warning: Function parameter or member 'all_list' not described in 'iser_fr_pool'
