Prasad J Pandit 4299b90e9b display: cirrus: check vga bits per pixel(bpp) value ...

In Cirrus CLGD 54xx VGA Emulator, if cirrus graphics mode is VGA,
'cirrus_get_bpp' returns zero(0), which could lead to a divide
by zero error in while copying pixel data. The same could occur
via blit pitch values. Add check to avoid it.
