Checklist (Please check before submitting)

• I reviewed the Contributing Guide.
• I reviewed the README file to see if the feature is in the major future work.
• I performed a cursory search to see if the feature request is relevant, not redundant, nor in conflict with other tickets.

Is your feature request related to a problem? Please describe.
Since both DirListData.EntryName and TempName are both OS_MAX_PATH_LENGTH, and and the os_dirent_t FileName is limited by OS_MAX_FILE_NAME, the first condition below can never be false:

FM/fsw/src/fm_child.c

Line 1496 in 9210c2d

if ((EntryLength < sizeof(DirListData.EntryName)) && ((PathLength + EntryLength) < OS_MAX_PATH_LEN))

Describe the solution you'd like
Remove, the second condition is sufficient (add comment)

Describe alternatives you've considered
None

Additional context
None
