LU-4423 ptlrpc: remove inline on non-inlined functions.

These three functions are never inlined.  The only time they
are used, their address is taken, and this forces them to
be compiled as stand-alone functions.  So having the "inline"
declaration is misleading.

Move the functions to the place where their address is used, and
remove the 'inline' tag.
