[PATCH] fbdev: mbx: fix a misspelled variable name

[Arnd Bergmann]

A recent cleanup introduced a build failure when a variable
was spelled incorrectly:

In file included from drivers/video/fbdev/mbx/mbxfb.c:881:
drivers/video/fbdev/mbx/mbxdebugfs.c: In function 'mbxfb_debugfs_init':
drivers/video/fbdev/mbx/mbxdebugfs.c:217:2: error: 'mbfi' undeclared (first use in this function); did you mean 'mfbi'?
  mbfi->debugfs_dir = dir;
  ^~~~
  mfbi
drivers/video/fbdev/mbx/mbxdebugfs.c:217:2: note: each undeclared identifier is reported only once for each function it appears in
drivers/video/fbdev/mbx/mbxdebugfs.c:213:21: error: unused variable 'mfbi' [-Werror=unused-variable]
  struct mbxfb_info *mfbi = fbi->par;
                     ^~~~
