51ab2e8ebd scst: Port to Linux kernel v4.19 
In Linux kernel v4.19 the function scsi_execute() has been replaced by the
following macro:

    /* Make sure any sense buffer is the correct size. */
    #define scsi_execute(sdev, cmd, data_direction, buffer, bufflen, sense,        \
                        sshdr, timeout, retries, flags, rq_flags, resid)   \
    ({                                                                     \
           BUILD_BUG_ON((sense) != NULL &&                                 \
                        sizeof(sense) != SCSI_SENSE_BUFFERSIZE);           \
           __scsi_execute(sdev, cmd, data_direction, buffer, bufflen,      \
                          sense, sshdr, timeout, retries, flags, rq_flags, \
                          resid);                                          \
    })

This macro only accepts a sense buffer that has been declared as an array
but no sense buffers that have been passed as a pointer to a function. To
avoid build errors, convert scst_scsi_execute() from a function into a macro.

directly, call it indirectly through scsi_req_init().
