arm64: ptrace: Always inline pt_regs_{read,write}_reg()

In subsequent patches we'll want to use pt_regs_read_reg() and
pt_regs_write_reg() in noinstr code.

To ensure noinstr safety, both functions must be inlined into their
caller. As both functions are marked as 'inline' rather than
'__always_inline', that's not strictly guaranteed, and the compiler is
permitted to generate out-of-line copies.

Mark both functions as '__always_inline' to ensure this.

There should be no functional change as a result of this patch.
