[LTP] [PATCH v2 3/3] memcg/memcontrol04: fix typos, redundant define and format specifiers

[Disha Goel <disgoel@linux.ibm.com>]

Fix typos in doc comment ('tempfs' -> 'tmpfs', 'becaue' -> 'because'),
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, not unsigned size_t), fix 'dont not'
-> 'do not' in inline comment, and remove now-unused <inttypes.h>
include.

Signed-off-by: Disha Goel <disgoel@linux.ibm.com>

v1 -> v2:
- Remove now-unused <inttypes.h> include (PRIdPTR was its only user)
- Split from combined memcontrol03+04 patch into separate patch per file
