examples/fb: Fix error message formatting and accuracy

Fix two error message issues in the framebuffer example:
* Add missing newline character to fbmem2 error message in fb_init_mem2()
* Correct mmap() error message that incorrectly referenced FBIOGET_PLANEINFO

These changes improve error reporting clarity and consistency for debugging framebuffer initialization issues.
