gpu: nvgpu: Read sm error ioctl support for tsg

Add READ_SM_ERROR IOCTL support to TSG level.
Moved the struct to save the sm_error details
from gr to tsg as the sm_error support is context
based, not global.

Also corrected MISRA 21.1 error in header file.

nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and
nvgpu_dbg_gpu_ioctl_read_single_sm_error_state
functions are modified to use the tsg struct
nvgpu_tsg_sm_error_state.
