fbdev: svgalib: Clean up coding style 



This patch addresses various coding style issues in `svgalib.c` to improve
readability and better align the code with the Linux kernel's formatting
standards.

The changes primarily consist of:
- Adjusting whitespace around operators and after keywords.
- Standardizing brace placement for control flow statements.
- Removing unnecessary braces on single-statement if/else blocks.
- Deleting extraneous blank lines throughout the file.

These changes are purely stylistic and introduce no functional modifications.
