Subject: [PATCH] sdm710-common: libqti-perfd-client: return a dummy value

Return a positive integer for perf lock acquire and release so
that Goodix/FPC fingerprint sensor blobs will not complain.

Goodix:
E [goodixHAL][gf_hal_milan_f_series]: goodix_perf_lock_acquire: Failed to acquire perf lock, err: 0
E [goodixHAL][gf_hal_milan_f_series]: goodix_perf_lock_release: Perf lock release error 0

FPC:
E fpc_tac : fpc_perf_lock_acquire: Incorrect params, Failed to acquire perf lock, err
E fpc_tac : fpc_perf_lock_release: Perf lock release error 0
