mwifiex: fix interrupt processing corner case in MSI mode

Browse source

As interrupt is read in interrupt handler as well as interrupt processing
thread, we observed a corner case issue for MSI in which interrupt gets
processed twice.

This patch moves interrupt reading code for MSI mode from
mwifiex_interrupt_status() to mwifiex_pcie_process_int() to avoid the
issue.
