Thorsten Blum 62c89e1992 crypto: octeontx - Fix length check to avoid truncation in ucode_load_store 
commit 5565a72b24 upstream.

OTX_CPT_UCODE_NAME_LENGTH limits the microcode name to 64 bytes. If a
user writes a string of exactly 64 characters, the original code used
'strlen(buf) > 64' to check the length, but then strscpy() copies only
63 characters before adding a NUL terminator, silently truncating the
copied string.

Fix this off-by-one error by using 'count' directly for the length check
to ensure long names are rejected early and copied without truncation.
