Subject: [PATCH 5.4 182/215] scsi: megaraid_sas: Remove undefined ENABLE_IRQ_POLL macro

From: Chandrakanth Patil <chandrakanth.patil@...adcom.com>

commit 07d3f04550023395bbf34b99ec7e00fc50d9859f upstream.

As the ENABLE_IRQ_POLL macro is undefined, the check for ENABLE_IRQ_POLL
macro in ISR will always be false. This leads to irq polling being
non-functional.

Remove ENABLE_IRQ_POLL check from ISR.
