[PATCH] scsi: osst: remove useless variable assignments in osst_int_ioctl()

[Gustavo A. R. Silva]

Value assigned to variable blkno at lines
4123:if (blkno >= 0) blkno += arg; and
4127:if (blkno >= 0) blkno -= arg;
is overwritten at line 4131:blkno  = STps->drv_block;
before it can be used.

This makes such variable assignments useless.
