[PATCH] staging: fbtft: Use %pe format specifier for error pointers

The %pe format specifier resolves error pointers to their symbolic
representation. Previously %ld with PTR_ERR() was being used, %pe is a
better alternative.

Fixes the following coccinelle warnings reported by coccicheck:
WARNING: Consider using %pe to print PTR_ERR()

Testing: I do not own the hardware, therefore I could not perform
hardware testing. Compile tested only.
