scsi: mac_esp: Replace bogus memory barrier with spinlock
[ Upstream commit 4da2b1eb230ba4ad19b58984dc52e05b1073df5f ]
Commit da244654c66e ("[SCSI] mac_esp: fix for quadras with two esp
chips") added mac_scsi_esp_intr() to handle the IRQ lines from a pair of
on-board ESP chips (a normal shared IRQ did not work).
Proper mutual exclusion was missing from that patch. This patch fixes
race conditions between comparison and assignment of esp_chips[]
pointers.
