QFontEngineFT: Fix Clang warning about using uninitialized variables.

Browse Source 
gui/text/qfontengine_ft.cpp(1743,5) :  warning: variable 'bytesPerLine' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
gui/text/qfontengine_ft.cpp(1743,5) :  warning: variable 'format' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]

The default branch is marked Q_UNREACHABLE, but apparently Clang does
not recognize it.

Task-number: QTBUG-50804
