drm/radeon: Fix ENOSYS with better fitting error codes in radeon_gem.c

srishanm · alexdeucher · commit db996e64b293 · 2023-07-27T14:59:30.000-04:00
Replace the error code from 'ENOSYS' to 'EOPNOTSUPP' for unimplemented
radeon_gem_pread_ioctl &amp; radeon_gem_pwrite_ioctl

Fixes the following:

WARNING: ENOSYS means 'invalid syscall nr' and nothing else.
