[LTP] [PATCH 2/2] memcg/memcontrol03-04: fix typos, redundant define and format specifiers

[Disha Goel]

Fix typos in doc comments ('tempfs' -> 'tmpfs', 'becaue' -> 'because',
'dont not' -> 'do not'), remove '#define TMPDIR "mntdir"' which
duplicates the definition already in memcontrol_common.h, replace
PRIdPTR with %zu for size_t arguments (PRIdPTR is for signed intptr_t),
and fix continuation line indentation in tst_res() calls.
