ANDROID: keychord: Check for write data size
keychord driver causes a kernel warning when writing more than
(1 << (MAX_ORDER - 1)) * PAGE_SIZE bytes to /dev/keychord.
In reality writes to this file should be much smaller, so
limiting data size to PAGE_SIZE seems to be appropriate.
This change checks write data size and if it's more than
PAGE_SIZE causes write to fail.
