Richard Fitzgerald 392cff2f86 firmware: cs_dsp: Use strnlen() on name fields in V1 wmfw files

[ Upstream commit 680e126ec0 ]

Use strnlen() instead of strlen() on the algorithm and coefficient name
string arrays in V1 wmfw files.

In V1 wmfw files the name is a NUL-terminated string in a fixed-size
array. cs_dsp should protect against overrunning the array if the NUL
terminator is missing.
