QCommandLinkButton: Don't reset icon on change to QStyleSheetStyle

d4c518b210ad56cb51c17e6e1b4a81b0deb7253c has implemented a reset of the
icon on a style change.

This has caused a regression, because it overrode an icon set by a
style sheet.

Do not reset the icon if the new style is a QStyleSheetStyle.

Amdends d4c518b210ad56cb51c17e6e1b4a81b0deb7253c.
