Either from Hindi -वाला (-vālā, "pertaining to") or from Hindi वाला (-vālā, "person in charge"), from Sanskrit पाल (pāla, "protector"), from Proto-Indo-European *peh₂- (“protect”). (Wiktionary)
In most cases, this is simply a phonetic misspelling by a person unfamiliar with the French term. However, in some cases, a relationship may be assumed with Arabic والله wallah meaning "by God" or "I swear to God!". (Wiktionary)
