skd: Remove useless barrier() calls
The purpose of barrier() is to prevent reordering by the compiler.
Since the compiler does not reorder calls to non-pure functions,
remove the barrier() calls from skd_reg_{read,write}{32,64}().
Since pr_debug() is able to report file name and line number
information, remove __FILE__ and __LINE__ from the pr_debug() calls.
