[ Upstream commit 70e37988db94aba607d5491a94f80ba08e399b6b ]

The way 'spin_lock()' and 'spin_lock_irqsave()' are used is not consistent
in this function.

Use 'spin_lock_irqsave()' also here, as there is no guarantee that
interruptions are disabled at that point, according to surrounding code.

Fixes: a97ec51b37ef ("nvmet_fc: Rework target side abort handling")
