gpu: nvgpu: replace tsgid input variable with pointer to a struct tsg_gk20a

Browse Source 
replace tsgid with a pointer to a struct tsg_gk20a in the function
gk20a_fifo_tsg_abort(). gk20a_fifo_tsg_abort needs to enumerate through
all the channels within the tsg as well as pass the tsg pointer to
other functions, qualifying the need to use a pointer instead as an
input parameter.
