staging: csr: remove CsrStrDup

Browse Source 
Use kstrdup() for the few places that called it, and remove
CsrUtf8StrDup() as no one calls that function.

NAME
CsrUtf8StrDup
DESCRIPTION
This function will allocate memory and copy the source string into the
allocated memory, which is then returned as a duplicate of the original
string. The memory returned must be freed by calling CsrPmemFree when
the duplicate is no longer needed.
PARAMETERS
source - UTF-8 string to be duplicated.
RETURNS
Returns a duplicate of source.
