Subject: [PATCH 4.14 144/211] scsi: megaraid_sas: Fix goto labels in error handling

From: Shivasharan S <shivasharan.srikanteshwara@...adcom.com>

[ Upstream commit 8a25fa17b6ed6e6c8101e9c68a10ae68a9025f2c ]

During init, if pci_alloc_irq_vectors() fails, the driver has not yet setup
the IRQs. Fix the goto labels and error handling for this case.
