memstick r592: make memstick_debug_get_tpc_name() static

Browse Source 
[ Upstream commit 434587df9f7fd68575f99a889cc5f2efc2eaee5e ]

There are no other files referencing this function, apparently
it was left global to avoid an 'unused function' warning when
the only caller is left out. With a 'W=1' build, it causes
a 'missing prototype' warning though:

drivers/memstick/host/r592.c:47:13: error: no previous prototype for 'memstick_debug_get_tpc_name' [-Werror=missing-prototypes]

Annotate the function as 'static __maybe_unused' to avoid both
problems.
