compat_ioctl: bsg: add handler
bsg_ioctl() calls into scsi_cmd_ioctl() for a couple of generic commands
and relies on fs/compat_ioctl.c to handle it correctly in compat mode.
Adding a private compat_ioctl() handler avoids that round-trip and lets
us get rid of the generic emulation once this is done.
Note that bsg implements an SG_IO command that is different from the
other drivers and does not need emulation.
