Revert "gpu: nvgpu: Dump offending push buffer fragment"

Channel and gpfifo allocations are entirely separated from each
other, however, the code here assumes that active channel means
that the channel also has a gpfifo.

This reverts commit a24602f094380539788696d1b1567a4f4d914b17 which
added gpfifo dump. Changing debug dumping to be safe requires
refactoring the channel release code to use proper locking.

Bug 1530226
