linux-yocto/uvesafb: print error message when task timeout occurs
Integrating the following commit to have a more informative error
message:
uvesafb: print error message when task timeout occurs
The driver waits for response from user space for a pending
task until a timeout (UVESAFB_TIMEOUT) occurs. But the
existing error message in later steps is a little obscure.
This patch throws out an error message when timeout happens.
