  Convert x86/lib/msr.c comments to kernel-doc notation to
eliminate kernel-doc warnings:

msr.c:30: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Read an MSR with error handling
msr.c:52: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Write an MSR with error handling
msr.c:91: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Set @bit in a MSR @msr.
msr.c:104: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Clear @bit in a MSR @msr.
