David Milburn 97651ea687 mtip32xx: fix user_buffer check in exec_drive_command
Current user_buffer check is incorrect and causes hdparm to fail

# hdparm -I /dev/rssda
 HDIO_DRIVE_CMD(identify) failed: Input/output error

/dev/rssda:

Patching linux-3.6-rc5 hdparm works as expected

# hdparm -I /dev/rssda
/dev/rssda:
