[ofa-general] [PATCH 1/2] [uDAPL v1] fix provider-specific compiler warnings

[Patrick Marchand Latifi]

Initialize ds_array_start_p otherwise the compiler would claim
that this variable could be used with an uninitialized value.

Makes the uDAPL providers now build successfully when using make
VERBS=<provider> (the -Werror flag was causing the build failure)
