From: Lorenz Brun <lorenz@brun.one>

The io_timeout property, introduced in c9b6609 (part of 6.0) is
silently overwritten by the hardcoded default value of 30 seconds
(DEFAULT_IO_TIMEOUT) in scsi_generic_realize because that function is
being called after the properties have already been applied.

The property definition already has a default value which is applied
correctly when no value is explicitly set, so we can just remove the
code which overrides the io_timeout completely.

This has been tested by stracing SG_IO operations with the io_timeout
property set and unset and now sets the timeout field in the ioctl
request to the proper value.

Fixes: c9b6609b69facad ("scsi: make io_timeout configurable")
