drm/crc: Cleanup crtc_crc_open function
This patch make changes to allocate crc-entries buffer before
enabling CRC generation.
It moves all the failure check early in the function before setting
the source or memory allocation.
Now set_crc_source takes only two variable inputs, values_cnt we
already gets as part of verify_crc_source.
Changes since V1:
- refactor code to use single spin lock
Changes since V2:
- rebase
Changes since V3:
- rebase on top of VKMS driver
