scsi: sg: Fix get_user() in call sg_scsi_ioctl()
get_user() expects the pointer to be pointer-to-simple-variable type, but sic->data is array of 'unsigned char'. It violates get_user() contracts. Explicitly take pointer to the first element of the array. It matches current behaviour. This is preparation for fixing sparse warnings caused by Linear Address Masking patchset.
