Ilias Tsitsimpis b32bd0a8ee target/transport: Always initialize bidi fields in se_cmd 
Fields t_bidi_data_sg and t_bidi_data_nents are set only in the presence
of BIDI commands. This means that the underlying code (for example TCMU)
cannot inspect them when the SCSI command is not a BIDI one.

Ensure the code always initializes these fields with the given values,
even when the SCSI command is not a BIDI one. Set t_bidi_data_sg to
sgl_bidi (which should be NULL for non-BIDI commands) and
t_bidi_data_nents to sgl_bidi_count (which should be 0 for non-BIDI
commands). This allows the underlying code to use these fields
unconditionally.
