scsi: target: tcm_qla2xxx: Remove BUG_ON(in_interrupt())

Browse Source 
tcm_qla2xxx_free_session() has a BUG_ON(in_interrupt()).

While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: the function is always invoked from
workqueue context through "struct qla_tgt_func_tmpl" ->free_session() hook
it is bound to.

The function also calls wait_event_timeout() down the chain, which already
has a might_sleep().

Remove the in_interrupt() check.
