[SCSI] qla2xxx: Change del_timer_sync() to del_timer() in qla2x00_ctx_sp_free().

Browse Source 
Using del_timer_sync() in the qla2x00_ctx_sp_free() function may cause a kernel
panic as it is not interrupt context safe and qla2x00_ctx_sp_free() may be
called from a softirq context.  Changing the call from del_timer_sync() to
del_timer() will make the function interrupt context safe.
