Subject: PCI: designware-ep: Move the function of getting MSI capability
forward
Git-commit: 6bfc9c3a2c70a987e6432925769ec1376a12aed0
Patch-mainline: v5.10-rc1
References: bsc#1179344
Move the function of getting MSI capability to the front of init
function, because the init function of the EP platform driver will use
the return value by the function of getting MSI capability.
