scsi: core: Release SCSI devices synchronously
All upstream scsi_device_put() calls happen from thread context. Hence
simplify scsi_device_put() by always calling the release function
synchronously. This commit prepares for constifying the SCSI host template
by removing an assignment that clears the module pointer in the SCSI host
template.
scsi_device_dev_release_usercontext() was introduced in 2006 via
commit 65110b216895 ("[SCSI] fix wrong context bugs in SCSI").
