[PATCH v2] auxdisplay: hd44780: Fix an API misuse in hd44780.c

[Haoxiang Li]

Variable allocated by charlcd_alloc() should be released
by charlcd_free(). The following patch changed kfree() to
charlcd_free() to fix an API misuse.

Changes in v2:

Sorry Geert, I didn't see your reply until after I sent the
second patch. I've merged the two patches into one, hoping
to make your work a bit easier! Thanks a lot!
